We use IAX trunks from our provider primarily as they are so much easier 
to configure and you only need one port open on your firewall/nat gateway.

SIP needs hundreds, if not thousands of open ports IIUC.

Yes, SIP requires very good, precise and complex stateful inspection 
from a firewall. You need 2 ports for each RTP stream, and these should 
be maintained by the firewall as media circuits are established and torn 
down.

Do you know about any voice quality issues with IAX, especially with a 
big call volime?

[asterisk-users] help on ${RTPAUDIOQOS}

2009-10-01 Thread Asterisk User
Hi All,

While reading about QoS, I came across ${RTPAUDIOQOS} and tried to use it in
my dialplan.
I had 2 sip extensions 555 and 666 and I called from 555 to 666, but
unfortunately no value for ${RTPAUDIOQOS} appeared on Asterisk CLI.

Would you please let me know what is wrong with my dialplan and/or what else
should be done to get the value of ${RTPAUDIOQOS}?

Following is my dialplan context where my call landed

[incoming_vpbx]
exten = _x.,1,NoOp(A call has come)
exten = _x.,n,Noop(${RTPAUDIOQOS})

exten = _x.,n,Dial(SIP/666,30,m)
exten = _x.,n,Hangup()
exten = h,1,Noop(***${RTPAUDIOQOS})


And here is what appeared on CLI...
-- Executing [...@incoming_vpbx:1] NoOp(SIP/555-b7a80948, A call has
come) in new stack
-- Executing [...@incoming_vpbx:2] NoOp(SIP/555-b7a80948,

What are you dialing?

If you have a remote box called [box_b] in sip.conf and you're dialing 
sip/1...@box_b, what do you get?

Have you played around with all the options?

Are you able to get a packet dump of how the packet should look?

If so, you may be able to add a sip header if necessary.

Mike –

It looks like you have externip set but no localnet setting.

You need to set localnet for your internal networks so that Asterisk knows when 
to properly apply the externip setting.

There is no such thing as an RTCP 'answer'.

 Can that be fixed?

If it is a real problem, of course it can be fixed. The first step to
doing so would be to actually provide enough details for others to try
to understand the problem.

 why does the busy not wait for 10 seconds before dropping the zap channel ?

Because (based on your log) the call came in over an ISDN circuit, and
when you run the Busy application Asterisk sends a 'BUSY' indication to
the calling switch, which then tears down the call. The timeout
specified to Busy() is only relevant for channel types where the calling
end will not drop the call on its own (like an analog channel).

[asterisk-users] Is there a way to get info who disconnected the call into CDR?

Hei!

 

Here's my problem. I have an Asterisk with SS7 and SIP trunks. Asterisk
version is 1.6. I'm setting up a custom CDR fields and I was wondering
is there a way to know who initiated a hangup? Asterisk must be aware of
that info somehow, cause in queue_log, that info is present
(completecaller, completeagent) Is there a way to get that info on the
regular SS7 to SIP (and vica versa) calls?

[asterisk-users] What are the reasons for VoIP echo?

2009-10-01 Thread Myles Wakeham
I have an Asterisk 1.4.2 system that has been installed for about 3 
months now in our home.  We converted all of our phones to SIP phones, 
and use two different trunk providers (BroadVoice for incoming  
FlowRoute for outgoing).

Most of the time its working flawlessly.  But about 1/3rd of the calls 
that come into us complain of an echo and what is best described as 
latency issues.  Its not consistent though.  I was on the phone with an 
insurance company yesterday for about 1 hour and the call was perfect (I 
originated the call which used Flowroute for the SIP provider).

What seems to be a pattern here is cell phones.  When we receive a call 
from a cell phone, or from certain people on certain phone systems, they 
consistently complain of echo in the call.  Its far less regular when we 
originate the call, which suggested to me that the problem might be with 
Broadvoice.  But I'm now hearing that us calling back the party doesn't 
always solve the problem either.

We upgraded our Internet feed (we're on a cable Internet through our 
cable company, with 12mb/s down, 1.5mb/s up) and that seems to have 
helped but not solved this problem.  From what I can see, its some form 
of latency issue.  We use IPCop as a firewall for our Internet access, 
but have turned off any IDS on it so that its running fast.  I can play 
online computer games through the network with no issues at all, so I 
don't think its slowing down the traffic and if it was I'd expect this 
problem to be occurring consistently on all calls.

Are there any tweaks that I can do with Asterisk to increase the network 
performance to reduce these issues?  Have others who have experienced 
this been able to identify the issues to external VoIP SIP providers 
only, or does our system have something to do with all of this?  At the 
time of the calls coming in, IPCop is telling me that we don't have more 
than 100K/s of bandwidth in use, and according to the network bandwidth 
graphs there, even with 2 people on the phone at the same time, the 
bandwidth never seems to exceed 300K/s, so I think we have plenty of 
headroom for this.  I checked with our cable provider for issues with 
modem latency, and they couldn't detect anything.  Again, I'm not 
experiencing any lag issues with computer games, particularly those that 
are heavy in interactivity, so I don't think that is the reason.

Any suggestions as to what could be tweaked would be greatly appreciated.

What kind of firewall are you passing through?

 

If it’s PIX or ASA, I’ve found the most reliable route is to enable SIP inspect

This way the PIX/ASA is responsible for “fixing” SIP and making the media work.

Re: [asterisk-users] INVITE Sending Local IP

2009-10-01 Thread Scott L. Lykens
Mike -

If your router/firewall does not have any kind of SIP protocol-specific support 
then you need to set up port forwarding on your router.

Forward udp/5060 for signaling, and the matching udp ports as listed in your 
rtp.conf, to your Asterisk box. Keep the externip and localnet settings in 
place.

Depending on how many ports are listed in rtp.conf you may choose to reduce 
this range but make sure the forwarding in your router matches the ports in 
rtp.conf. Read the below links to help determine an appropriate number of ports 
if you choose to change it.

Some more information for you: 

http://www.voip-info.org/wiki/view/NAT+and+VOIP
http://www.voip-info.org/wiki/view/Asterisk+config+rtp.conf

PIX and ASA are specific models of firewalls from Cisco. They include a SIP 
protocol-specific fixup or inspect function that takes care of passing 
media through the firewall for you as long as you don't try to fix it 
yourself first.

no echo issues at all. Also cable modem but only the slow version. 
There is a Linksys router between the Asterisk box and the cable 
modem.  Usually VOIP echo is the other end. There should be no way 
other than having the volume on your SIP phones way too high to get 
local echo. In the past it's been suggested on inexpensive phones 
with this problem to take apart the handset and make sure the path 
from the speaker to microphone is blocked or filled with sound 
insulation.  I'm using Aastra 480i phones and that's never been a problem.

[asterisk-users] DTMF problems during a message play

2009-10-01 Thread Barton Fisher
I'm using the latest asterisk-1.4.26.2 and no zaptel trunks used, all SIP. 

I have one user that is having problems once he connects to asterisk. 
He's dialing from his home phone (pstn) to a Vitelity DID (SIP Trunk) 
which goes to my asterisk  IVR. 

If he presses a dtmf during any message, the press is ignored unless the 
press was a #, 0 or *.  Otherwise, he needs to wait for the message to 
stop before the press is hear.


I've tried all the suggestions found searching the wiki, so I ask here 
if there is something else I can try.  The Vitelity trunk is set up as:


dtmfmode=rfc2833
disallow=all
allow=ulaw

Thanks, Bart

2009-10-01 Thread Martin
Maybe the GSM carrier is disconnecting you ???
Just a wild guess. They sometimes do that if they have to free
the channel ... for a better paying customer :)

I actually see the TOS setting in iax.conf, but the default (commented out)
is EF - which doesn't even match a valid bit combination according to
voip-info wiki
 
If this is the right place, what TOS value are people using succesfully over
an ADSL connection?

Yes the tos setting is the right place and EF is an acceptable value. EF 
is the differentiated services code point (or dscp) for expedited 
forwarding. The sample sip.conf defaults tos_audio to EF as well. The 
iax.conf wiki page only shows the old type of service values which are 
considered deprecated. Look at this page for more info on diffserv:

http://www.voip-info.org/wiki/view/DiffServ

As for what to use, well, that depends on whether your upstream provider 
even honors what you set. They may use the old type of service values, 
they may use dscp or they may ignore what you put there entirely.

Re: [asterisk-users] QOS/DSCP for IAX?

2009-10-01 Thread Dave Fullerton

Yea, kinda, sorta. The DSCP is six bits, which occupy six of the 8 bits 
in what is/was the type of service byte in an IP packet. Three of the 6 
DSCP bits reside over the old precedence field and three reside over the 
old low delay, high throughput and high reliability fields (those three 
often referred to as TOS). The DSCP code points are designed to be 
backwards compatible with the PRECEDENCE portion of the old tos. The low 
delay, high throughput and high reliability bits have been redefined and 
no longer are backwards compatible. When doing my research I found some 
web sites displayed the tos byte in different bit-orders (cisco with 
precedence first, wikipedia with precedence last). It was confusing as heck.

I also have some old equipment that does not understand DSCP/Diffserv. 
What I ended up doing was making asterisk and phones use the dscp code 
points and my old router software queue packets based on what it sees in 
the precedence field. Works like a charm.

Good luck.

Is that coming from Asterisk?

It seems strange that Asterisk would reject the call unless you have 
settings in asterisk.conf to do this. You've said you've already 
increased the file descriptor limits - did you do this in the console 
you were using to subsequently run Asterisk from?

Do you get any errors in the Asterisk console?

Re: [asterisk-users] TDM410P - False Answer Supervision

2009-10-01 Thread Danny Nicholas
Assuming you're using POTS, you probably won't have much luck with this.  If
you are calling yourself, you can do Dial(DAHDI/8c/3602045,20) and asterisk
won't process the line until you pick up and punch a dtmf key.  If you are
using E1 or PRI, there is more hope for you.

Re: [asterisk-users] What are the reasons for VoIP echo?

2009-10-01 Thread Myles Wakeham
Ira writes:

 Very similar to what I have. Also Flowroute for outgoing but others
 and a TDM400 for incoming. Since upgrading to 1.6.2 from 1.2.28 or so
 and figuring out DAAHDI and HPEC on the new version there have been
 no echo issues at all. Also cable modem but only the slow version.
 There is a Linksys router between the Asterisk box and the cable
 modem.  Usually VOIP echo is the other end. There should be no way
 other than having the volume on your SIP phones way too high to get
 local echo. In the past it's been suggested on inexpensive phones
 with this problem to take apart the handset and make sure the path
 from the speaker to microphone is blocked or filled with sound
 insulation.  I'm using Aastra 480i phones and that's never been a 
 problem.

That's interesting.  Our setup is almost identical to yours.  We have 3 
different SIP phones, one being an Aastra 480i.  I have a Grandstream 4 
Line one, and my wife has a Grandstream 2 line one.  Both are relatively 
high-end phones (not inexpensive ones).  The echo issues we've seen 
don't appear to be any different regardless of the phones in use.  And 
strangely we never actually experience them on our end.

The problem is always reported to us by someone calling in to us.  This 
is what suggested to me to migrate my DID numbers over to them, rather 
than keeping them with Broadvoice.  I think I might do that as a 
precaution anyway since its not likely to be a big problem for us to do it.

The volume on our phones are not loud.  I use a headset with my phone 
most of the time, which seems to give a better quality call to the other 
end, but there's not an issue with volume that could cause it.

I am curious about the fact that you said after upgrading to 1.6.2, your 
problems went away.  I didn't start with that version because it wasn't 
the current production version at the time.  Do you think it would be 
beneficial to migrate to that version for me?

I've been trying to get this to work on and off for a while now, and it's 
time to get serious.  If someone would like to get paid for getting this 
to work please contact me off-list (I also have a Google Wave invite if 
you're interested).  The solution (and the steps we take) will of course 
be posted back here and you will also have my eternal gratitude.

Thanks,

Re: [asterisk-users] What are the reasons for VoIP echo?

I am curious about the fact that you said after upgrading to 1.6.2, your
problems went away.  I didn't start with that version because it wasn't
the current production version at the time.  Do you think it would be
beneficial to migrate to that version for me?

I would expect not. I originally installed from an all in one disk 
and then removed most everything but asterisk. I always had issues 
with channels getting stuck and needing to reboot occasionally. I had 
tried 1.4 a few time and never got past 6 calls before it segfaulted 
so I stayed with 1.2, always kept up to date. When I built my new 
machine using an Atom and CentOS 5 I decided to use the 1.6.2 beta 
because I beta test a lot of software and I'm comfortable with the 
risks. It was probably silly, but all the issues I had before with 
stuck channels and other nonsensical problems are now a thing of the 
past. Echo has rarely been a problem for us once I got the echo 
cancellation working properly on the incoming only POTS line. I don't 
recall it happening on outgoing calls which are now either Flowroute 
for domestic or CallWithUs for international.  Occasionally I'll get 
problems to New Zealand or Australia, but calling back usually fixes 
it. No clue why, but at 1.5 cents/minute I can put up with it.

[asterisk-users] IAX2 Call rejected, CallToken Support required

2009-10-01 Thread Klaverstyn, David C
Hi All,

 

I am using Asterisk 1.4.26.2 and I am getting the following problem
making connections to this server.  My other servers are Version 1.2.x
which have no problems and this 1.4.26.2 server can call the other 1.2.x
servers.

 

The error is:

chan_iax2.c:4251 handle_call_token: Call rejected, CallToken Support
required. If unexpected, resolve by placing address 192.168.25.250 in
the calltokenignore list or setting user priv requirecalltoken=no

 

I have seen posts that suggest using:

calltokenoptional = 0.0.0.0/0.0.0.0

or

   calltokenignore=xxx.xxx.xxx.xxx

 

Using the above cause asterisk not to display the error but nothing
occurs in the CLI.  If I enable debug I see the following with the
option calltokenoptional = 0.0.0.0/0.0.0.0 in iax2.conf in the general
section.

Re: [asterisk-users] What are the reasons for VoIP echo?

2009-10-01 Thread Martin
if a user calling you hears echo of himself then it's the fault of
your sip device/sip phone.
The manufacturer must be using a cheap or an open source echo canceller ...

try getting a different sip device made by some 'normal' company like
polycom or linksys/cisco

Re: [asterisk-users] What are the reasons for VoIP echo?

2009-10-01 Thread John A. Sullivan III
I'm quite new to all this but I was under the impression that most
electrically induced echo was at the physical interface to the PSTN.  If
one is using SIP trunking, I would think this would point to a carrier
issue.

We also hit an interesting problem with echo today but I don't think
this is the issue Myles is having.  We installed fairly high end phones
with full duplex speakerphones.  Callers are having a bad problem with
echo when the users use the speakerphone.  Because it is full duplex
rather than half, if the speakerphone volume and speakerphone mike
volume are turned up, the callers are indeed hearing themselves by
virtue of the higher quality full duplex!

Re: [asterisk-users] What are the reasons for VoIP echo?

2009-10-01 Thread Martin
Are you saying there are half duplex phones out there  with half
duplex speakerphones ?

All analog phones are full duplex ...

Anyways the echo can be created by the analog phone even when it's
connected to the
sip ata or even the sip phone ... then you usually have acoustic echo
which goes from speaker
to microphone of the handset ... that should be cancelled by the sip
phone/device... or someone out there will
hear echo

 this is the issue Myles is having.  We installed fairly high end phones
 with full duplex speakerphones.  Callers are having a bad problem with
 echo when the users use the speakerphone.  Because it is full duplex

 volume are turned up, the callers are indeed hearing themselves by
 virtue of the higher quality full duplex!

 Assuming you're using POTS, you probably won't have much luck with this.  If
 you are calling yourself, you can do Dial(DAHDI/8c/3602045,20) and asterisk

 Hello All,

 Can anyone help me with False Answer Supervision problem with TDM410P

 everything works fine except the Answer supervision...

 When the call hits Asterisk it sends the call to one of the TDM410 card
 and the call is answered immediately while the call is still in
 progress... Here is the debug output: -
