Re: [asterisk-users] Alternative to Local channel

[Eric Wieling]

You can't set the variable in globals?  I don't know if functions work 
in globals, but it is worth a try.


[globals]
LSESSION=${STRFTIME(${EPOCH},,%Y-%m-%d %H:%M:%S)}

I used to use the local channel to create a global variable

(dialplan)

[default]

exten => s,1,Set(GLOBAL(LSESSION)=${STRFTIME(${EPOCH},,%Y-%m-%d %H:%M:%S)})

to that end, I modified cli.conf

[startup_commands]

originate local/s extension s@default = yes

But now I upgraded to Asterisk18 and there is no longer a local channels

Does anybody have any idea of a workaround?

Re: [asterisk-users] Setting codec on originating (calling) channel with chan_pjsip (SIP_CODEC_INBOUND equivalent)

[Eric Wieling]

I suspect most people simply don't care.   Transcoding between ulaw and 
g722 is not CPU intensive and Direct Media doesn't work when NAT is 
involved (which would the case for most people).

Re: [asterisk-users] AGI script commands

[Eric Wieling]

You have to read stdin to accept the data Asterisk sends when the AGI 
starts before you can send any AGI commands to Asterisk.   Also, "agi 
set debug on".

Re: [asterisk-users] Get channel variables via ARI/AMI

[Eric Wieling]

If you want to do more than just get headers from the INVITE, then 
you'll need to use an actual SIP Proxy like Kamailio.


On 6/26/23 15:03, TTT wrote:
It looks like if I call Getvar and pass PJSIP_HEADERS() I can get the

the PJSIP_HEADER function will only return the headers from the INVITE 
of the _inbound_ channel.


If that’s correct, how would I get the headers from the outbound channel 
(second leg of the bridged call) INVITE ?  Or will PJSIP_HEADERS() in 
fact return the header from either inbound out outbound legs?

 For some reason Asterisk is not replacing the private IP with my public IP

Is that all that's needed for Asterisk to replace the from IP with the external

Multicast doesn't connect. There is no session. RTP is thrown out onto 
the network using multicast, and then devices pick it up. Asterisk has 
no idea what (if anything) is receiving it. You'd want to do a packet 
capture to see what is being multicast.




Does this mean things like DIALSTATUS won't work as expected?

Re: [asterisk-users] Exec two commands with ExecIf

The dialplan is a very complicated config file.  It is often repetitive

 If you want that, use an AGI.


In this case, just call it an "Asterisk-ism" and move on.  You'll find 
plenty more of them.

Re: [asterisk-users] Dial() after the h extension has been invoked?

[Eric Wieling]

Create a spool file from the 'h' extension to generate the call.

On 11/12/21 11:56, Antony Stone wrote:

Hi.

I have a setup which comprises some "front-end" Asterisk servers which have
SIP trunks to external providers, and very simple dial plans, and some "back-
end" servers which only talk to the front-end machines, and have the majority
of my dialplan logic on them.

I use Dial() commands with custom SIP headers to pass information (eg: about
the current state of a call) between the front-end and back-end machines, and
this works very well.

However, I can't use a Dial() command in the h extension to notify the other
machines that a call has ended and they can now delete their state information
about that call.  If I try to, I get the error:

app_dial.c:2245 in dial_exec_full: Caller hung up before dial.

I guess i can see why Asterisk complains about being asked to Dial() after the
inbound call leg has ended, but in this case I have a reason for doing so.

Can anyone suggest how I might be able to do this?  I need to perform a Dial()
command after an inbound channel has hung up.  I do not expect the Dial() to
bridge to anything (the context being dialled simply does some database
manipulation and then hangs up without even bothering to answer).


Any suggestions welcome :)

On the outgoing pjsip endpoint, set "moh_passthrough = yes".   If you then

upstream server.


So... how do I put the incoming call on hold, when the dumb client I'm

I already know (from this list) that Asterisk as a SIP client cannot do ore
than (a) place a call, (b) answer a call, and (c) hang up a call.

So, I'm still intrigued as to how you think this might be possible.

If it *is* possible, I'd be really interested, but all my researches so far
suggest that Asterisk, acting in the middle like this, just cannot add the
necessary "put call on hold" which the original client cannot do.



With Asterisk, keep Asterisk in the media path with direct_media=yes and 
use DTMF to hold, transfer, and other features using features.conf. 
Asterisk has to stay in the media path when NAT is involved anyway.


I doubt anything except Asterisk or other B2BUA software can do what you 
want.

You could switch to PJSIP and avoid most of this silliness.

PJSIP is different so there is a learning curve, of course.

3381 is the number they want to dial into my asterisk.   3382 is
the registered extension to their system.

I think at first I was only using 3381. That was the extension I
registered. There was no 3382.  Something was going wrong there
also. (Might have been a similar error),
and I could not get that to work either.

Jerry



Well my issue has changed now.  I have dropped the 3382. Changed back to 
3381.   So I am registering 3381 to the other server.

The other server is 10.35.229.5.  My IP is 10.35.229.11.
I have two network cards.

The issue is that the call comes in but the user hears no audio.
There is any crazy networking going on - why would the user not hear audio ?
Thanks

Re: [asterisk-users] SIP Source Port

[Eric Wieling]

Kamailio is useful when you want to do weird, non-standard, or unusual 
stuff with SIP.   You could send your outgoing connections to Kamailio, 
which could then send the connection out with the required source port.


Have you considered using a not stupid provider?

Can anybody point me in the right direction?  I am using PJSIP.


If you are referring to an outgoing connection, it's not possible to 
configure PJSIP to do this. For an outgoing connection the system uses 
an ephemeral port as the source.

Regardless of if there is a way in dialplan, I'd vote for an AGI to
avoid
what I suspect will be a bunch of fragile, difficult to maintain
dialplan
with quoting issues.

But, I am an AGI kind of guy :)

Some may argue that dialplan MAY be more performant, but I have an AGI
that sets over 2,000 channel variables from MySQL tables and nobody has
ever complained about call startup time.

the call before the FCC, and liable for any illegal call. Every owner of a PBX that sends

"borrowed", you need to get the signature service urgently or your business 
will stop terminating calls. You cannot self-sign, you cannot get around it, the calls 
will either go to straight to voicemail or fail. Even worse, the carries wil play a fake 
voicemail and charge you a fee, something that some already a are doing when they detect

Don't even think about Transnexus, because they use 302 Redirect with a

world for Stir-Shaken and Asterisk. I know it sounds arrogant but it is

you need to connect to my service. I am an approved Service Provider from the 
FCC. If you keep thinking this is not happening, it is, and your business will 
disappear overnight.
The issue is that Vicidial, for example, does not provide res_odbc and 
func_odbc, so you need to solve that first with Vicidial. Then you can apply 
the code I provided earlier and your calls with have a legal, binding 
signature. The carriers verify each signature and discard the ones that fail 
the cryptography test.


Sounds like you're trying to sell/direct people towards a service that
you've created.  Feel free to do so on the -biz list but the -users
list isn't the right place for that sort of thing.


But the question is, are his statements correct that we need some
service -- not necessarily his -- to sign the call before sending it
to our normal carrier, or will the normal carrier -- whoever -- sign
the call if they know the number?

mysql -u anonymous -h 208.73.232.47 -e "call

If your caller-ID is a valid US number and not a wireless number (that 
is a NO-NO for the FCC), we sign the call as 'C', if you use your own 
DIDs, something we can verify as legit, then we sign as 'B', and if 
you use our DID as caller ID, we sign as 'A', full attestation.
Please email to venefax at g mail if you have any questions. Do not 
think you can do business as usual. The wild west of VOIP is coming to 
an end. But we can keep you in business if you follow the rules.

Re: [asterisk-users] Troubleshooting load issues

Try setting transcode_via_sln=no in /etc/asterisk/asterisk.conf and

Hi,

I have an Asterisk box which has an IVR that plays random gsm files. The

CPU usage along with the load seems to jump around. With about 500 
callers it hovers between 250-400% CPU (so 2.5 to 4 cores) which seems 
reasonable. Every so often the load average spikes. The idle never drops 
below 85%. When the load average spikes I see a lot of kworker threads 
and the CPU usage tends to (not not always) go up as well. How would I 
go about seeing what in Asterisk is causing the spike? The box is locked 
down and only takes calls from an OpenSiPS box. There is nothing else 
running on the box.

Totally possible... We're currently doing what you suggest with

This allows for fast updates at any node, and synchronizes via

There are other replication solutions out there, but nothing as

Dovid,

I'm not much of a PHP person, but in perl, i check the process id that's

I think php uses pcntl_fork().

Re: [asterisk-users] why doesn't extension "s" work ?

[Eric Wieling]

Think of "s" as meaning "stupid" because calls from devices too stupid 
to send the dialed number are routed to the "s" extension.


Any incoming calls which includes the dialed number would NOT be sent to 
extension "s", those calls will match whatever the dialed number is.

    same=>n,

But when a call comes in to the gv-voice context, "s" doesn't match the 
extension:


res_pjsip_session.c:2991 new_invite: Call from 'gv-voice' 
(UDP:10.10.10.80:5062) to extension '' rejected because 
extension not found in context 'gv-voice'.


I thought "s" (as in start ?) would match any extension sent to that 
context.

We’ve got a client with an old paging system that (supposedly) just

it, it doesn’t auto-answer the call, so paging never happens.

Re: [asterisk-users] branching in extensions.conf?

[Eric Wieling]

If you want your dialplan code to look pretty, use AEL.

Is there any less cumbersome way of doing conditionalized/branching in

Granted the particular above example could probably be better written
to simply modify $ARG2 based on ${SIP} rather than having two Dial()
branches, but using the above as just an example for wanting to have
branches, is there a less cumbersome way?

Re: [asterisk-users] Various extensions ring once and go to voicemail - Thomas Peters

[Eric Wieling]

From https://wiki.asterisk.org/wiki/display/AST/Timing+Interfaces:

res_timing_dahdi uses timing mechanisms provided by DAHDI. This method 
of timing was previously the only means by which Asterisk could receive 
timing. It has the benefit of being efficient, and if a system is 
already going to use DAHDI hardware, then it makes good sense to use 
this timing source. If, however, there is no need for DAHDI other than 
as a timing source, this timing source may seem unattractive. For users 
who are upgrading from Asterisk 1.4 and are used to the ztdummy timing 
interface, res_timing_dahdi provides the interface to DAHDI via the 
dahdi kernel module.


res_timing_timerfd uses a timing mechanism provided directly by the 
Linux kernel. This timing interface is only available on Linux systems 
using a kernel version at least 2.6.25 and a glibc version at least 2.8. 
This interface has the benefit of being very efficient, but at the time 
this is being written, it is a relatively new feature on Linux, meaning 
that its availability is not widespread.

Carlos and Stefan (and other who have helped):

I DON'T HAVE the res_timing_timerfd.so file. Can I build it? Recompiling

/usr/src/asterisk-1.8.7.0/res/res_timing_timerfd.c

Why I have 1.8.23 and 1.8.7 I don't know. Asterisk on this system is version 
1.8.7.0.

NEXT QUESTION: There are NO timing modules listed in /etc/asterisk/modules.conf at all. 
The only ones that are explicitly loaded are format_wav format_pcm format_mp3 and 
res_musiconhold. And there are "preload" directives for pbx_config.so and 
chan_local.so.

Is res_timing_dahdi.so getting loaded somewhere else? Or is it a default of 
some kind?

SYSTEM TIME OF DAY CLOCK which someone asked about, seems accurate. I did
watch -n1 date
and watched the time tick up, perfectly synchronized to my mobile phone. It 
might be off by a second or so, I'd have a hard time knowing for sure. NTPD is 
running, but not working for some reason. I fixed it (ownership of ntp.conf 
wrong) so now ntpq -pn returns a server ID.

So what would you suggest? (And thanks in advance.)

Thomas

I've had some good experience with

res_timing_dahdi

both when we ourselves were still on 1.8 and now with us on Asterisk 13 as well.

To force usage of a certain timer, specify in your modules.conf, e. g. to force 
use of DAHDI timing only, I did the following in my modules.conf:

.
.
.
load => res_timing_dahdi.so
noload => res_timing_pthread.so
noload => res_timing_timerfd.so

That said, we have had some weird issues trying to run Asterisk in virtual 
machines - all our instances (16 of them) are physical machines.

We did a deployment at Azure in a Centos 7 "stock Azure" VM awhile ago and it 
suddenly lost the capability to encode .gsm audio files. All .gsm files the virtualised 
Asterisk 13 instances produced were all corrupt and no player would want to play the .gsm 
files. Neither could SOX convert them to anything. So we had to switch over to .wav, and 
then use a mixmonitor hook and manually convert the .wav files back to .gsm in SOX after 
each recording was written by Asterisk in .wav format. There were no errors logged, 
Asterisk just mysteriously lost the capacity to encode .gsm files when running on the 
Azure VM instance we had.

So quite probably the virtual environment / hypervisor you're using is part of 
the issue and switching timing modules around won't solve anything...

Have you checked that the system time is sane, and that one second on a stop 
watch externally to the VM instance, equates to one second inside it?

Because the symptoms described could indicate that the clock in the VM is just 
running too fast - or that some timing implementation detail inside

It is not possible to configure Asterisk for this. The chan_pjsip
module only does normal reinvites with SDP when configured to pass
through MOH signaling.


This is the answser I feared ;-)
Thanks for replying.

If someone has a clue for alternatives (softphones, hardphones, ...), 
I'll curious to know

properly because it was waiting for the AGI to return... The

Due to this problem I started looking for some option to timeout the 
AGI call and return to the dialplan after XYZ seconds and so this 
would protect Asterisk preventing the dialplan to get stuck due to 
some external script problem that is actually outside of Asterisk 
control. Does Asterisk provide some control of this sort? I searched 
around and could not find any.

Any idea is appreciated!

Re: [asterisk-users] getting real sip status after dial

[Eric Wieling]

My actual dialplan hangupcause handling is in AGI and AEL, so the 
dialplan below has not been tested.


Don't use HANGUPCAUSE_KEYS, the order of the channels varies.  Save the 
channel name while the dialplan is in the predial handler like below. 
MASTER_CHANNEL is used to avoid silly issues with the scope of the 
out_chan variable.


[test]
exten => _X.,1,Set(CHANNEL(hangup_handler_push)=caller_hangup,s,1)
 same => n,Dial(SIP/my-peer/12125551212,30,b(test_pre_dial^s^1))

[test_pre_dial]
; while in the handler save the channel
exten => _X.,1,Set(MASTER_CHANNEL(out_chan)=${CHANNEL{name})
 same => n,Return

You should be able to use the caller hangup handler to get tech 
hangupcauses like "SIP 480 Temporarily Unavailable".


[caller_hangup]
exten => 
s,1,Noop(HANGUPCAUSE(${MASTER_CHANNEL(out_chan)},tech)='${HANGUPCAUSE(${MASTER_CHANNEL(out_chan)},tech)}')

exten => n,Return

Remember the incoming leg of the call and the outgoing leg of the call 
are different channels.  Make sure you are giving HANGUPCAUSE the 
correct channel.

Re: [asterisk-users] getting real sip status after dial

I think HANGUPCAUSE is channel agnostic.

See: core show function HANGUPCAUSE

Some thing like this IIRC:
Set(my_cause=${HANGUPCAUSE(${CHANNEL(name)},tech)})

Remember the incoming leg of the call and the outgoing leg of the call 
are different channels.  Make sure you are giving HANGUPCAUSE the

Re: [asterisk-users] How to execute priorities following a caller hangup in a successful Dial?

[Eric Wieling]

Don't use the _. pattern.  Ever.

The call has two channels so it needs two hangup handlers, something 
like this, though I've not tested it.


[some_context]
exten => _X.,1,Noop
 same => n,Set(CHANNEL(hangup_handler_push)=my_caller_hangup_handler)
 same => n,Dial(SIP/number@peer,b(pre_dial^s^1))
 same => n,Hangup

[pre_dial]
exten => s,1,Set(CHANNEL(hangup_handler_push)=my_called_hangup_handler)
 same => Return

See: https://wiki.asterisk.org/wiki/display/AST/Pre-Dial+Handlers
and https://wiki.asterisk.org/wiki/display/AST/Hangup+Handlers

Re: [asterisk-users] What does pct mean?

Could this gap in sequence numbers caused by a codec change generate

This doesn't make any sense to me, either. There can't be more packages
transmitted than received. It's the same codec in and out and it's been
running exactly the same time.
Lost and Percent (pct) are not calculated by counting packets. Those 
are calculated from the sequence numbers in the RTP frame.


For example let's say you start the receiver (Asterisk) at Sequence 
#1then something happens and it jumps to sequence #5000.  The 
audio might be fine, but now the stats say 4998 packets were lost. Why 
is there a bizarre sequence jump?  Hard to say.  I have seen it 
because of bugs that eventually get fixed on the CPE, or even when 
there is a change of codec (or re-invite) mid-call.  I would not worry 
too much about this unless you can reproduce it and can address it 
properly at the CPE level.  A packet capture will clearly confirm what 
I am referring to here. Just look at every Sequence # in the RTP flow 
and you will see the jump.



...Receive. .Transmit..
Count    Lost Pct  Jitter   Count    Lost Pct    Jitter RTT
188K  0    0   0.000    188K   16641K 8809   0.000   0.026

       
There are 188K received and 188K transmitted. Pct is unknown - what's 
Pct?



Still 8809 does not sound like a percentage to me  so there is 
something wrong with either the label or the value.
 From what's in the code, you can see it's clearly a lost Packet 
count not a percentage.

So I guess Pct in this case is short for "Packet".

Re: [asterisk-users] Handling a long-running agi on hangup-handler?

[Eric Wieling]

Asterisk (after 1.4?) sends the AGI a HUP when the call hangs up.

Try setting your script to ignore the HUP signal and make it fork and go 
into the background so Asterisk thinks the process has completed.


In PHP ignore HUP:

    pcntl_signal(SIGHUP, SIG_IGN);

In PHP fork and become a short lived daemon:

    $pid = pcntl_fork();
        if ($pid == -1) {
        die("could not fork");
        } elseif ($pid) {
        exit; // we are the parent
        }
        // we are the child
        // detatch from the controlling terminal so we don't become a 
zombie when we die.

        if (posix_setsid() == -1) {
        die("could not detach from terminal");
        }

I know that hangup handlers

So it's no surprise that my speech to text agi which takes 8 seconds

However, can anyone think of a way round this? So, once the caller has 
hung up, I need to take one of the channel variables, and pass it to a 
python agi script which then does speech to text.


In-call, it works fine. After hangup, it doesn't. Which is correct, 
but any thoughts on ways round this?


Thanks.

Interesting. The announcements for 13.19.0 and 15.2.0 you have made here
both list all issues which have been fixed in the section "Bugs fixed in
this release". However,

ASTERISK-27480
ASTERISK-27452
ASTERISK-27337
ASTERISK-27319

seem to be security related (according to the short explanation texts in
the announcements) and have been fixed both in 15.2.0 and 13.19.0.

I am wondering why 14 does not suffer from them, or -if it suffers from
them- why they are not considered security related there.

I highly respect your work and don't want to steal your time since I
have probably seriously misunderstood something, but could you please
shortly explain what the string "Security: " (aka "(Security)" and with
other wordings) at the beginning of the short explanation text for an
issue exactly means?

Thank you very much,

Re: [asterisk-users] Answered time on channel

[Eric Wieling]

From the hangup handler specification:

Hangup handlers are an alternative to the h extension. They can be used 
in addition to the h extension. The idea is to attach a Gosub routine to 
a channel that will execute when the call hangs up. Whereas which h 
extension gets executed depends on the location of dialplan execution 
when the call hangs up, hangup handlers are attached to the call 
channel. You can attach multiple handlers that will execute in the order 
of most recently added first.

I don't see how fail2ban would help. asterisk isn't rejecting 
anything. There's no attempt with username/password.


How could I use iptables to "lock it down" ? We get sip calls from all 
over. Is there something about the incoming packet we could use ? For 
instance , any packet containing a VIA instruction ? For that matter, 
can SIP be configured to drop any VIA request?




fail2ban is most useful for blocking registration attempts.    I handle 
non-registration call attempts by allowing guests, point them to a jail 
context, which runs Log(WARNING,fail2ban='${CHANNEL(peerip)}')   I set a 
fail2ban rule to match that line logged from Asterisk.

Re: [asterisk-users] Answered time on channel

[Eric Wieling]

Don't use an 'h' extension, use a hangup handler.
Use the MASTER_CHANNEL() function to set variables to ensure they are 
always set in the "top most" channel.  Below is an untested example, but 
is inspired by dialplan code I use in production.  Maybe it will help.


[outbound] ; this is called on the incoming (caller) channel
exten => _X.,1,Noop
 same => n,Set(MASTER_CHANNEL(start_timestamp)=${STRFTIME(,,%s.%3q)})
 same => n,Set(CHANNEL(hangup_handler_push)=hangup_handler,s,1)
 same => n,Set(MASTER_CHANNEL(callid_ingress)=${SIPCALLID})
same => n, *** unrelated dialplan, AGIs, etc. ***
 same => n,Dial(SIP/${EXTEN}@1.1.1.1 
,,U(answer_handler)b(pre_dial_handler^s^1)g
 same => n, *** dialplan for the caller when the callee hangs up first, 
not run when caller hangs up first.  use it to try dialing another 
destination, play intercept to caller, etc. ***



[pre_dial_handler] ; this is called on the outgoing (callee) channel
exten => s,1,Noop
 same => n,Set(MASTER_CHANNEL(callid_egress)=${SIPCALLID})
 same => n,Set(MASTER_CHANNEL(dial_timestamp)=${STRFTIME(,,%s.%3q)})
 same => n,Return


[answer_handler] ; run on outgoing (callee) channel, but sets 
answer_timestamp in the caller channel

exten => s,1,Noop
 same => n,Set(MASTER_CHANNEL(answer_timestamp)=${STRFTIME(,,%s.%3q)})
 same => n,Return


[hangup_handler]  ; run on incoming (caller) channel, use to do final 
post call cleanup

exten => s,1,Noop
same => n,Set(MASTER_CHANNEL(hangup_timestamp)=${STRFTIME(,,%s.%3q)})
  same => n, ***post call cleanup AGIs, dialplan, etc.***
same => n,Return

Hi,

I have a dial plan where I need to notify an external system when a 
call was answered and when the call hung up. In both requests the 
start time needs to be the same. My Dialplan looks something like this:



[outbound]
Exten => _X.,1,Dial(SIP/${EXTEN}@1.1.1.1 
,,U(call-answer-from-carrier))


Exten => h,1,NoOp(ANSWERED_TIME: ${ANSWEREDTIME} >>> DIAL_TIME: 
${DIALEDTIME} >>> HANGUP_TIME: ${EPOCH} >>> ANSWERED TIME 
${MATH(${EPOCH}-${ANSWEREDTIME},int)})


[call-answer-from-carrier]
Exten => s,1,Noop(CALL WAS ANSWERED AT ${EPOCH}
Exten => s,n,Agi(some_script.py)

Now in theory the hangup time of the call (${EPOCH} in the h 
extension) minus the answered time should be the same as the noop from 
my subroutine. I am finding that some times they match and some times 
they are off by a second. My issue is that the external system expects 
the answered time to the same for when we call it from the SubRoutine 
as well as from the h extension. I assume the difference is based on 
the microsecond of when we look at EPOCH how DIALEDTIME is rounded.


Any tips on how I can get the same answered time across the board?

TIA.

Dovid

Re: [asterisk-users] General Kernel practices on CentOS

That only applies to DAHDI, not Asterisk.

I add exclude=*kernel* to /etc/yum.conf so the kernel doesn't get

If you installed asterisk from source, you need to recompile it after

This will compile & install asterisk modules with latest installed

Re: [asterisk-users] RS485 Audio device

[Eric Wieling]

If cable can be pulled , you have a couple of options.

Long Reach Ethernet from Cisco is rated for 5,000 feet. Multi-mode fiber 
with fiber/ethernet media converters on each end would work and 
electrically isolate the two ends of the cable. Both are way overkill 
from a capacity standpoint, but sometimes there's nothing wrong with 
overkill. Put an ATA on the far side.

Re: [asterisk-users] Multiple phones when one is unregistered

[Eric Wieling]

The dial application dials devices not extensions.   The only way to 
"dial" an extension from the dialplan is to use chan_local.

So does the Dial command go directly to the registered device or does
it use the extension?  I was assuming that it was going to the

SIP registration matters.  That would be a good thing since many
extensions also ring the user's cell phone and that would be annoying
if they were at home when someone came to the office door.

You should set your verbosity to 3 and then reproduce the call and paste 
the CLI output.   It is pointless to troubleshoot without the CLI 
output.  The warning is expected when the phone is offline and does not 
cause the issue you are experiencing.  It almost looks like Local/

The dialplan below cannot go to voicemail, either something else is

The idea is that any of the three users can answer the phone to let
someone in.  The problem is that if, say, user2 unplugs his phone then
the call immediately goes to his voice mail and the other two do not
have the ability to open the door.

Is there any way to direct only to phones in a list that are currently
registered?  I am sure that I can write a rather convoluted extension
to check for registrations and create a dial command but I am hoping
that there is an easier way so that I can create these types of
extensions for other clients easily as well as being able to add and
remove destinations quickly.

My test dialplan sets up variables like these:

exten => _X.,n,Set(T1="Example name" )

If I just apply the regex operator (:) on T1 using regexp RX, like this:

Currently I am working around the issue by using REPLACE() to strip

Did you include func_shell in your Asterisk build?

Fortunately, it's no biggie to build a missing module, because the
"make"
command explicitly keeps track of everything it has already done
and does not need to do again.  Just cd into the folder with your
Asterisk source, run `make menuselect` and select "func_shell" 
(under dialplan functions).  Then run `make` and finally `make

install`.

Re: [asterisk-users] Migrating asterisk 11 to 13: some callers get no ringback tone any more

[Eric Wieling]

I don't know the default setting for progressinband in the code, but it 
is documented in Asterisk 11's sip.conf.sample as defaulting to never.  
Maybe the docs were fixed since Asterisk 11.


from 11.21.x sip.conf.sample:

;progressinband=never   ; If we should generate in-band ringing 
always
; use 'never' to never use in-band 
signalling, even in cases
; where some buggy devices might not 
render it
; Valid values: yes, no, never Default: 
never

The default in 13 is "no" which still allows early media through. That

Yes, because it's doing inband progress using a media stream.

It's not the default.

FreePBX may not use inband progress for that scenario, causing it to
send out of band ringing instead.

Asterisk does not have the concept of ring groups, this is a FreePBX
construct. Asterisk itself does allow the option to be set on an
individual basis for the entries in sip.conf.

Your characterization may be true but Skype works much better than SIP 
when it comes to sound quality.

I have SIP softphone with Asterisk server and Skype on the same

Skype just works better over the same network.

Re: [asterisk-users] Caller ID Names

[Eric Wieling]

Are the phones exposed to the internet (even using NAT)?  If so there is a good 
chance these calls are not coming through your PBX but are coming in direct 
from someone, usually scammers.

Polycom has a config option to disable accepting calls from unknown devices.  
No idea if Cisco has something similar.

[asterisk-users] Failsafe AGI using AEL

[Eric Wieling]

For the mailing list archive and for anyone else interested.

A few years ago we needed to automatically run a second AGI if the first AGI 
failed i.e. a failsafe setup.  Mainly because I'm not a very good programmer.

The code below is very similar to what we use in production.  This code is also 
at http://pastebin.com/LBaLhdfJ for a while.  sm stands for Switch Manager 
(get your mind out of the gutter), the name of one of our internal Asterisk 
projects.  

/*

This script runs an AGI, if the AGI fails, a circuit breaker will trip.
The breaker causes this script to skip running the primary AGI on and only run 
the failsafe AGI until the max calls or max seconds.
Once max calls or max seconds elapse the breaker is reset on the next call and 
everything goes back to normal.

GLOBAL VARIABLES

the machine with the extra long DTMF is using hardware DTMF decoding where the 
working machine is using software only.

Re: [asterisk-users] Investigating international calls fraud

[Eric Wieling]

I’ve seen the following exploits of Asterisk / FreePBX boxes:


1)  Default PlcmSpIp username and password for Polycom provisioning

2)  Insecure SIP usernames and secrets

3)  FreePBX GUI accessable from the internet

4)  OS remote exploit (maybe ssh/ssl exploit)

Mitigation options:

1)  Don’t use an easy to guess or default password on provisioning servers.

2)  Use secure secrets.  Users never enter the secret so we use a 32 char 
random string of characters for the password

3)  Don’t allow connections to port 80 from off-site.

4)  Make sure your OS and SSH/SSL is updated packages are updated.

Contact your carrier and ask about any possible fraud detection.Verizon SIP 
service has that feature.   I don’t think Level 3 has.   Don’t know about 
CenturyLink.   I also recommend locking down the system very tight with IP 
tables – only allow whitelisted traffic rather than only blocking blacklisted 
traffic.

Fraud is a constant issue for everyone.

Subject: [asterisk-users] Investigating international calls fraud

Hello,

I'm investigating a situation where there was a hundreds of minutes of calls 
from an internal SIP extension to an 855 number in Cambodia, resulting in a 
crazy ($25,000+) bill from the phone company. I'm investigating, but can anyone 
provide some feedback on what's happened here? I'm investigating how this 
happened as well as what types of arrangements can be made with the phone 
company (CenturyLink in Texas).

Some details:
* PBX is located in Texas
* Phone carrier is CenturyLink
* FreePBX distro running asterisk 1.8.14
* source SIP extension is Mitel 5212, firmware 08.00.00.04, default admin 
password (argh!). Phone is used by many different people.

More PBX setting details:
* inbound SIP traffic is not allowed through the firewall
* internal network is not accessed by many
* FreePBX web interface

Questions I have at this moment:
1) how were the calls placed? Was the Mitel SIP phone hacked somehow? Asterisk 
PBX?
2) how does this typically get sorted out with the phone company? they are 
charging $6.25 per minute for the Texas to Cambodia calls. The phone system 
owners are at fault, but how have these situations worked out in the past?

I'll be tightening things up, but any feedback is appreciated.

Thanks,
Steve

Re: [asterisk-users] sip show channelstats reliable?

[Eric Wieling]

I've seen something similar with Adtran SIP gateways.When a re-invite 
happens the Adtran gets all confused about call stats and marks the 
pre-reinvite leg of the call as losing large numbers of packets.BTW, IIRC 
reinvites happen when a codec changes or the channel switches to T.38.

Also Adtran SIP gateways appear not to support OPTIONS packets when running in 
SIP proxy mode, which is very annoying. At some point I'll try and arrange 
a slugfest between Digium and Adtran and they can figure out why it doesn't

Subject: [asterisk-users] sip show channelstats reliable?
I am seeing lots of lost packets when running the command sip show channelstats 
at the CLI.

There are issues across multiple Asterisk servers I am trying to diagnose but 
everything I read seems to point to this command being pretty unreliable.

Can I trust the info this command shows?

I am showing lots of lost packets in sip show channelstats but I can't see any 
packet loss when pinging the same IP's to/from.

Since I don't 100% control the network my gear is on, I need something outside 
of Asterisk to show the network engineer to convince here and myself that there 
are network issues.

All I have is the loss that's shown from this command with no real network 
stats to back it up.

Is there a magic command in CentOS anyone can recommend to diagnose and match 
up the issues shown in Asterisk using this command?

Moving gear around on the network changes the info Asterisk shows a LOT. For 
example, if I point traffic to the main physical gateway I get loss to a 
particular customer's IP (their PBX), if I move it to another place on the 
network (as a VM) their IP is good and other customers IP's start showing loss 
using the channelstats info.

Driving me freakin' crazy. It does appear there are network issues causing my 
troubles but I can't get help if I can't point to some hard and fast issues 
outside of Asterisk.

The only thing I have right now is collissions showing on one of a few of our 
pfSense devices but they are virtual running on XenServer, still this would 
indicate a problem in my opinion.

Thanks in advance for any assistance on this issue. Stepping back from the 
ledge now LOL

Re: [asterisk-users] Passing literals with commas to subroutine [SOLVED]

The easiest way is to escape the commas is with a \ (backslash).

 Hi,
 
 Let's say I do:
 
 Set(data=xxx,yyy)

 My subroutine will only receive xxx for ARG1. How can I pass a literal
 with a comma to a single argument in a subroutine?
 
 (The point is: when calling the subroutine I do not know if the variable
 has a comma or not.)

O.K.  I've managed to set myself up a temporary Asterisk box, so I was able to 
do some testing without risking bringing down a production server  :)  And I 
have managed to put together a solution, if you can call it that.

If you put speech marks around the argument, like so:
 Gosub(my-sub,s,1(${data}))
then what actually comes through in ${ARG1} is
 xxx,yyy
(complete with the speech marks).  But at least that comma is protected.  So 
then within my-sub, you just need to evaluate ${ARG1:1:-1}, ${ARG2:1:-1} c. 
to strip off the first and last characters  (skip one, show all but one).  


It's a bit ugly -- but so is a lot of stuff written in the Dialplan.  Just 
because a language is Turing-complete, doesn't mean any code written in it is 
going to be pretty.  But you might be able to mitigate some of the ugliness 
with comments  (introduced with a semicolon in Dialplan, because the comment 
mark is a valid digit).

Re: [asterisk-users] Finish extension (avoid dialplan to silently continue in the next priority of another extension)

[Eric Wieling]

Hangup handling in Asterisk is horrible enough to make the Buddha cry.

The (mostly working) solution I came up with was

1)  Attach a hangup handler to the source channel as soon as possible in 
the dialplan to do whatever post call work which needs to be done.

2)  Use the “g” and “F” options to Dial to play any needed intercept 
messages required after one leg of the call hangs up.

Hi,

I have run into a strange behaviour:

[ctx-test]



exten = h,1,NoOp(*** hangup ***)



exten = s,1,NoOp(*** ${EXTEN} ***)

 same = n,...

 same = n,...

 same = n,Hangup()

Strangely, the h extension continues on the priority 2 of the extension s. 
Maybe this is caused by the use of same? How can I make sure that an extension 
is really ending, something like:

exten = h,1,NoOp(*** hangup ***)

 same = n,RellyEndHere()

For subroutines there is the Return() application, but this can not be used 
generally in contexts. Is there any application to finish processing the 
extension in the context?



Thanks,

Daniel

[asterisk-users] Weird SIP stuff

[Eric Wieling]

We are seeing something weird we haven't come across before. It seems they are 
sending us a different IP in the SIP from URI, than the IP they are actually 
sending us the traffic from.

Basically, the traffic is coming from 65.211.180.237 but the header is:

f: 
sip:+1347545xxx@199.173.94.80:5060;user=phone;tag=4-45026-159e4a6-995949f-159e4a6


Does anyone know if this is normal and how I might make it work with Asterisk.  
 Incoming calls are not matching the we auth on IP only

I doubt the person cares, if you don't like people top posting then stop 
reading their messages.  If someone top posts, nothing you do will make them 
stop top posting.   Complaining about something you cannot change just wastes 
everyone's time.I have a rule which deletes messages with top post in

Re: [asterisk-users] PBX hacked: why hundred of calls to the same number ?

We set up our servers to allowguest=yes and autocreatepeer=yes and use a global

OK, been messing with Asterisk for a long time and I have my opinion on where 
the issues lies but sometimes it's just nice to see what others think that can

Here goes..

Inbound calls flow like this:
Tier 1 Provider (SIP)  Asterisk 1.8  Name Brand PBX - Calls work fine

Outbound calls flow like this:
Name Brand PBX  Asterisk 1.8  Tier 1 provider (SIP) - Calls work fine


Problem is being reported on that many (not all) calls have no audio when they 
are forwarded.

Example of forwarded call:
Inbound call comes in from Tier 1 Provider  Asterisk 1.8  Name Brand PBX

Name Brand PBX then forwards the call back out to users cell phone:
Name Brand PBX  Asterisk 1.8  Tier 1 provider

No audio a large percentage of the time.


It's my opinion that the Asterisk box only sees the forwarded call as a regular 
outbound call and forwards it on to the Tier 1 provider then to the users cell 
phone.

I don't see how Asterisk even knows or cares if it was forwarded within the 
Name Brand PBX. The Name Brand PBX is the one making the connection of the 
inbound and outbound call. All other inbound and outbound calls are fine, audio 
is only lost when the Name Brand PBX connects the two calls and creates the 
forward.

Thoughts?

Hi,

Is there anything I can do with this problem? Re-installing Asterisk does not 
solve this and the problem still persists. Or is there any other logs or 
configurations I can provide to help figure out why Asterisk is removing lines 
from the sdp?

Any ideas would be greatly appreciated! I also tried removing everything under 
/etc/asterisk/ and make samples to restore any errors I could have had in my 
configurations, then restoring my minimal configuration: asterisk.conf, 
extconfig.conf, extensions.conf, res_mysql.conf and sip.conf. This did not help.

(in case this message comes double, I just canceled posting of previous similar 
one as it was too big)

cheers,

Re: [asterisk-users] Change codec when dial from SIP to DAHDI

You will find not transcoding much less useful that one might imagine.

 That article is in the development section of the wiki. While that
 doesn't mean any of the information there is necessarily wrong, its
 purpose was to coordinate development efforts, not to define behavior
 for end-users.

 In this particular case, portions of that page only affect chan_pjsip:

   thanks a lot for the hint! you really save my day!
   I was thinking about studying freeswitch, since people said
freeswitch can do that without transcode. now i will spent my time to
study chan_pjsip, and hope it can fix the problem. i really want to
stay with asterisk :)

   thanks again for your kindly help!!

Re: [asterisk-users] read digits from the user through php agi script

[Eric Wieling]

I’m not going to help you debug your code, but I wanted to post part of a 
function from one of our internal AGIs which reads auth codes using a simple 
IVR.  The code is ugly but it might be helpful to you.   This code is released 
to the public domain.

// no pin provided, get pin from caller
$agi-answer();
usleep(25);

$try = 1;
$bad_pass = FALSE;
$auth_start_time = microtime(TRUE);
while ($try  4) {
if ($try == 1) {
$agi-exec(Read, pin,/igc/sounds/cc-bong,$pinset_len,,1,3);

} else {
$agi-exec(Read, 
pin,please-enter-yourdigits/$pinset_lendigitaccess-code/igc/sounds/cc-bong,$pinset_len,,1,5);
}
}
$temp = $agi-get_variable(pin);
$pin = trim($temp[data]);

if ($pinset_verify == 1  $pin != ) {
$temp = array_search($pin, $pins);
if ($temp !== FALSE) {
$agi-set_variable(SM_START, $sm_start + (microtime(TRUE) - 
$auth_start_time));
$agi-exec(CELGenUserEvent, \SM,status = OK, cause =000, 
detail = Verified PIN, pin = $pin\);
return array(status = OK, cause =000, detail = 
Verified PIN, pin = $pin);
}
} else if ($pinset_verify != 1  $pin != ) {
$agi-set_variable(SM_START, $sm_start + (microtime(TRUE) - 
$auth_start_time));
$agi-exec(CELGenUserEvent, \SM,status = OK, cause =000,

Re: [asterisk-users] Asterisk 11.9.0 PRI no ring indications

[Eric Wieling]

Ringback problems are a pain in the neck to troubleshoot.   You don't mention 
your endpoint, but if the endpoint is sip, play around with the prematuremedia 
and progressinband options in sip.conf.The comments for these two settings 
in sip.conf.sample are completely and totally confuzing.  Try different 
compications and see if any of them make any difference.

Audio passes fine, I can even specify a default music on hold to play

Re: [asterisk-users] Asterisk secure fine tune - stop attack

[Eric Wieling]

If we don't need to allow access from outside the USA we block access from all 
non-ARIN IP addresses by using iptables.   This takes care of at least 80% of 
attacks.

I enabled guest access and pointed all guest calls to an IVR which auto 
disconnects the call after a while (2 min seems good) if there is no response.  
 That took care of most of the remaining attacks.

I'm considering enabling auto create peer and routing calls to the same IVR as 
above.

We also use fail2ban, but mostly for non-SIP attacks.

Before enabling any guest access be ABSOLUTELY SURE you know how to do it 
without causing security issues.

With your dialplan with g option on external trunk, if the call finishes the 
boss's leg of call also gets disconnected. So the next instruction would make a 
call to secratary, however with no one on other end.

  We are currently migrating from a Nortel pbx to Asterisk and we
 have been able to convert most of the functions that people are used to
 but there is one I have no clear idea how to do.  The scenario is:

  Boss calls secretary from outside the office to get connected to
 another outside destination.  The secretary dials the destination and
 then trasfers call to the boss.  When boss finishes with that person
 they want to send the call back to the secretary in order to make
 another connection or simply to talk to the secretary.

  The first part is not a problem, but after the boss finishes his
 call how can we send the call back to the secretary?  I was thinking of
 using a conference room but how would the secretary know when the boss
 has finished?  Anyone know how to handle this scenario?

I haven't tested this, but my initial thought would be to create a special 
context or extension that the secretary could route through when doing the call 
transfer. The Dial application could be called with the 'g' option to continue 
the dialplan at the next priority when the call hangs up. Something like a 
normal call transfer would just dial the number as normal, but for the special 
transfer, you could prepend the dialed number with a #.

For example (using a local US dialstring, change to fit your needs):

; This is a normal external call.
exten = _NXXNXXX,1,Dial(SIP/your_external_trunk/${EXTEN})
  same = n,Hangup()

; This is a call that should be transfered back to the secretary's extension 
when external call is finished
exten = _#NXXNXXX,1,NoOp(Special Dial for Boss/Secretary Transfer)
  same = n,Dial(SIP/your_external_trunk/${EXTEN:1},,g)
; First call has ended, now we go back to the secretary)
  same = n,Dial(SIP/1234)
  same = n,Hangup()

That's at least where I would start with my testing and then develop the 
solution from there.

Re: [asterisk-users] Custom SIP-header not present in call Asterisk to Asterisk

[Eric Wieling]

Try Hangup(123) where 123 is whatever hangup cause you want to send back to 
the caller.   The calliing Asterisk server will get the valuse back in 
HANGUPCAUSE variable.

Subject: [asterisk-users] Custom SIP-header not present in call Asterisk to

Hello,

I have a situation where a call comes in to my Asterisk server B. This call 
comes from another Asterisk server A. I want to tell to this server A why my 
server B hangs up.

So just before hanging up, I add a custom SIP-header :

exten = s,n,SIPAddHeader(X-My-Hangup: MaxChan)
exten = s,n,Hangup()


But I notice that this extra SIP-header is not send within the SIP-reponse :

Hello,

I have tried sending Hangup(321) on Asterisk server B to Asterisk A but when I 
read HangupCause on Asterisk A it always is '21'.

Good idea, but it does not seem to work.



Kind regards,

Jonas.

Both apps were configured with identical (codec) settings so I don't see 
how it would require transcoding. If you did get it to work I would 
appreciate it if you could tell me which clients you used, the Asterisk 
version, the OS and the relevant Asterisk config.

Thanks,
Patrick

core show codecs does not show VP8 on my Asterisk 11.  I don't recall why we 
are not using H.264.  The novelty wore off long ago and few of our staff use 
video calling anymore.

Thanks Eric. The obvious difference is that your co-worker was using 
H.263/H.263p while Bria uses H.264 or VP8. videosupport=yes was present 
in my sip.conf so it might be the codec. Time for more tinkering.

Re: [asterisk-users] PRI timing settings

NXXNXX is the correct format of CallerID numbers in NANPA.   The leading 1 
is not part of any NANPA phone number.   Toll free area codes are also not 
valid for CallerID.

Re: [asterisk-users] PRI timing settings

[Eric Wieling]

CallerID Name doesn't really matter.  Either your carrier will remove it when 
handing the call off to the next hop or the terminating carrier will ignore any 
CallerID name data and do a name lookup in their own database using the 
CallerID number.   This is why your CallerID name can be different depending on 
which carrier is used for the receiving phone number.
