[Asterisk-Users] Automatic setup of calls between two external lines

2005-07-26 Thread Rob Scott
Is it possible to automatically set up a call between two external
lines?
I would like Asterisk is call a cellphone number, wait for it to answer,
and then call another cellphone, when that answers connect the two
together.
I assume it is possible but can someone point me how to do it.

Thanks.

RE: [Asterisk-Users] IAX2 attempts native bridge when notransfer=yes

2005-07-22 Thread Rob Scott
This comment comes up fairly regularly and is confusing people.
Why doesn't it say that it failed so we know?
The way it is now it kind of leaves you hanging there and you don't know
if the transfer happened or not.
And why was it even attempted if it is obvious that transfer is off? 
(I know it can depend on the remote side.)

 Any ideas what I'm doing wrong?  This is driving me crazy.

Don't worry.  The attempt a native transfer function is called, logs
that it attempts it, then notices the notransfer=yes and fails the
transfer.

So nothing happens.

[Asterisk-Users] IAX over HTTP

2005-07-21 Thread Rob Scott
For work environments where you only get HTTP or HTTPS access, what is
the feasibility of doing IAX over HTTP?

I have heard of projects such as stunnel.

Has anyone tried something like this?

I did a quick search but didn't come up with much.

HTTP uses TCP. Too much overhead. Add SSL on to that and you have a huge
amount of overhead. The end result would be poor and choppy sound

RE: [Asterisk-Users] Problem with DTFM and complex international setup

2005-07-12 Thread Rob Scott



I don't think so.

Your problem seems to do with your not being able to use an 
IAX client to transmit DTMF tones properly somehow.

I am using a normal phone to connected to FWD which then 
connects to an Asteriskserver using IAX protocol.
The point is that between the phone and the far Asterisk 
server, I guess that the tones are being sent as audio and not as inbound 
messages.
So the far Asterisk server has to listen to the audio for 
the tones.
On an unstable connection, it is sometimes missing a tone, 
or hearing a break in a tone and thinking that it is two identical tones, which 
results in a mis-interpreted number sequence at the other 
end.

So I think the problems are different.

RE: [Asterisk-Users] Debugging zaphfc + PBX integration

2005-04-15 Thread Rob Scott
If you your board into an ISDN wall socket and it works then you are
acting as a terminal so you are in terminal mode.

Now, how are you connecting to the PBX?
If you are connecting to an ISDN extension on the PBX, then still you
have to match the kind of connection, whether it is point-2-point or
point-2-multipoint.
Then it should work.

If you are connecting it to an external line on the PBX, then it will
have to be in station mode and also you have to work out p2p or p2mp and
also have an ISDN crossover cable (not an ethernet crossover cable).

So a lot for you to work out.

I have successfully got a zpahfc card working on an extension of our PBX
and also a PRI card working on an external PRI line of the PBX, so it
should work for you in the end.

RE: [Asterisk-Users] cannot dial two phones using zap

2005-04-14 Thread Rob Scott
Looks normal to me.
What Dial with the '' means is that both lines ring, but the first one
to answer is connected on the call.

From you trace it looks like Zap/3-1 which is your number 206 answered
the call, so the other line goes to hangup.

The Dial with '' is used to implement call teams where all the phones
ring but the first one to pickup gets the call and the other phones stop
ringing.

RE: [Asterisk-Users] Acceptable voice time delay

2005-04-12 Thread Rob Scott
Around 250ms max. Over that and you will have the walkie-talkie effect
you are experiencing.
So with you 600ms delay you are way over the top.

There is also the delay on the call on the PSTN side you have to take
into account.
For example, I am in Europe and making a call to the UK via Voipjet is
usually OK.
But making a call to Romania is a lottery. Sometimes it is great,
sometimes the delay is huge.
And that has nothing to do with the internet delay which is more or less
constant at around 180ms for me.

But with 600ms, which is over half a second, you have problems.

[Asterisk-Users] LDAP and Asterisk

2005-04-01 Thread Rob Scott
I am looking to roll out an Asterisk VoIP implementation to our 200
employees.
So far I have hooked up the Asterisk box to our Elmeg PBX via a PRI
interface card and have that working, plus about 30 test users on Xlite
softphones.

Up til now all the configuration has been done by hand editing
extensions.conf and sip.conf and voicemail.conf as needed. I would
rather this was kind of automatic - when a new user is created then
everything is already setup for them.

We are in a (horror of horrors) Microsoft environment running Windows
XP, Windows 2003 Server with AD and a sizable number of Sun and Linux
boxes for development (we are an IT development shop).

So what springs to mind is someone how connecting Asterisk to AD and
using some spare fields in AD to hold extension numbers and the like and
querying through an LDAP interface.
Kind of like Realtime but using LDAP.

Does anything like this currently exist?

Short answer is no. You should always turn it off on any client you

Longer answer is that is is being worked on and should be available any
day now (although that has been the case for some months).
Also someone is working on porting it to SIP as well as IAX2.
No idea if the new work will tell your if the client is using silence

I will reply to my own question in a case the answer is of use to others.

I rebooted my Asterisk server and now it seems to work OK again.
I suspect that after a while the zaphfc BRI interface has problems and needs a 
reboot.
I have seen different problems like this, i.e. problems that occur over time 
especially with answering calls, with the zaphfc drivers before.

A reboot usually cures it for a while, but it would be great if such a thing

Looking at that list, the easiest way would be to disable all your USB

you don't need USB. In general, just turn off all the things you don't

Yes.  Digium cards must be on their own IRQ or you will have weird

RE: [Asterisk-Users] Goto and E1 line

2005-03-19 Thread Rob Scott
You should have set up the two cards as zaptel as a different group in
the zapata.conf.

Then if you want to dial your pbx you are dialing out of Asterisk, so
you use the Dial command.
Assuming that the PBX PRI link is in group 2 in zapata.conf

Something like:

exten = ,1,Dial(Zap/g2/${EXTEN})

Is what you want if you are dialing extension  on your hard PBX.

[Asterisk-Users] Any 24 (or 30) way FXS PCI cards?

2005-03-19 Thread Rob Scott
It seems to me silly to have a T1/E1 card to connect to a channel bank
when you could just have a 24/30 way FXS card in the slot in the first
place.

Does such a thing exist?

Wouldn't Digium have a lot of customers if they could produce one for
say  $1000 retail?

RE: [Asterisk-Users] TE110P experiance

2005-03-11 Thread Rob Scott
I have noticed the following:

   - the PCI ID of the card seems to change over time which means that
loading the module does not always recognise the card, only way to reset
this is to power cycle the machine

   - you cannot unload the module once it is loaded, it hangs the
machine, which also means if you have automatic shutdown scripts for
restarting the machine then the machine will hang on reboot

One of the LEDs shows the status of the connection.
If it is off, then it is not active, i.e. zaptel drivers not loaded.
If red then bad connection i.e. it is not talked to the other end,
usually a wiring problem
If green then everything OK.
Could also be a yellow state but I haven't seen that.

Once you get it working, leave the thing up is my only advice.
It is a shame that it is not bug free, neither the hardware nor the
software so far.
I don't know what Digium want to do about the hardware.
I hope there is a firmware fix rather than having to mess with the
actual physical hardware.

[Asterisk-Users] Asterisk provides ring tone?

2005-03-08 Thread Rob Scott
I have an Asterisk box with TE110P PRI connected in net mode to a PBX.
Both are PRI EuroISDN.

The connection seems to work OK but when calling from Asterisk to the
PBX through an Xten, the Xten client does not get a ringing tone when
the PBX phone rings.
Is it possible to set this up?
Is there some zaptel or zapata setting for this or is it something that
needs to be in extensions?

Thanks for you help.

RE: [Asterisk-Users] jitterbuffers - suggested settings

2005-02-08 Thread Rob Scott
Apparantly the new one will do things like interpolation so that if
packets are lost it will generate new ones to fill the gap. The current
jitterbuffer doesn't do that so you get silence on packet loss. There
are a bunch of other features too that I don't remember, but that was
the most interesting to me last time I looked.

RE: [Asterisk-Users] Bristuff and incoming call problems

2005-02-04 Thread Rob Scott
I have exactly the same problem.
It was also the same with RC3.
It seems that after a couple of days of working fine, at some point
incoming calls fail but outgoing calls still work (or I would hear user
complaints earlier).

For the lack of ring problem, I do the following in extensions.conf:

[fromexternal]
exten = s,1,Ringing
exten = s,2,Wait,3
exten = s,3,Answer
exten = s,4,Wait,1
exten = s,5,Background(enter-ext-of-person)

So Asterisk singals a ringing tone for 3 seconds so that the caller's
phone has a chance to ring, then answers and plays the 'enter the
extension of the person you want to call' thing while at the same time
listening for digits.

I don't know if this is the right or expected approach but it works for
me.

Hi list!

I have some strange problems with Asterisk 1.0.5-BRIstuffed-0.2.0-RC5.

Very regularly asterisk seems to lose connectivity with the ISDN line.
If you try to call in you get the information tone that the number is
not in use. Outbound calls do stil work however. Unloading the modules
and reloading them and start/stop asterisk will solve the problem.

Another problem that occurs regularly : When you make an inbound call to
asterisk the calling party does not get the tone that the phone is
ringing on the receiving end. The line just seems completely dead untill
the phone is picked up and you can hear the other party. Is this an
asterisk / bristuff problem or something for the telco to sort out? Who
should generate the ringing signal to the calling party?

Thanks!!!

RE: [Asterisk-Users] Odd behaviour between Grandstream and Xlite

2005-02-04 Thread Rob Scott
I allow them to us any codec except speex (which seems to crash Asterisk
when used from an Xlite).

But it would be good if the user could choose their preferred codec
because with a softphone on a laptop sometimes you are on a connection
with good bandwidth to Asterisk and sometimes somewhere with terrible
bandwidth so you want to use a low bandwidth codec.
If Asterisk chooses for you then the codec choosing feature on the Xlite
is pointless.

RE: [Asterisk-Users] Bristuff and incoming call problems

2005-02-04 Thread Rob Scott
Sure you can put whatever you like in the answering config.
That is just mine because after dialing an incoming number the caller
dials an extension number that Asterisk uses to complete the call.

Junhanns does post on this group occasionally so I guess he watches it
but I haven't so far seen any useful messages on how to solve this
problem.

A behaviour I did notice once was that if you dialed in and then waited
about 4 seconds then you did eventually get a ringing tone, which
suggests that it was connecting but waiting for some timeout before
following the context code; i.e. it was working but had a timeout or was
working extremely slowly. Next time to thing behaves badly I will check
if this is still the behaviour.

If it doesn't get fixed then I will probably use a script that stops
asterisk, reloads the modules, and starts asterisk again and runs it at
say 5am every morning. Not ideal but what can you do?

The weird thing is that sometimes tyhe caller does hear the phone
ringing, and sometimes the line is dead.

I will try your workaround, will it also work without playing the
message for an extension? I use it at home and it sounds a bit silly :)

Are these bugs known at Junghanns?

 Subject: [Asterisk-Users] Bristuff and incoming call problems

 Hi list!

 I have some strange problems with Asterisk 1.0.5-BRIstuffed-0.2.0-RC5.

 Very regularly asterisk seems to lose connectivity with the ISDN line.
 If you try to call in you get the information tone that the number is 
 not in use. Outbound calls do stil work however. Unloading the modules

 and reloading them and start/stop asterisk will solve the problem.

 Another problem that occurs regularly : When you make an inbound call 
 to asterisk the calling party does not get the tone that the phone is 
 ringing on the receiving end. The line just seems completely dead 
 untill the phone is picked up and you can hear the other party. Is 
 this an asterisk / bristuff problem or something for the telco to sort

 out? Who should generate the ringing signal to the calling party?

 Thanks!!!
 Remco

I guess it should show a double zero because there is already a zero

[Asterisk-Users] Odd behaviour between Grandstream and Xlite

2005-02-03 Thread Rob Scott
Hi,

I've got an Asterisk box with grandstream and xlite clients on it.
No here's the thing:

  - I grey out all the codecs on the Xlite except for GSM
  - I call the Grandstream from the Xlite, the Xlite uses the GSM codec
and the Grandstream uses ulaw, with Asterisk doing the conversion,
everything fine
  - I call the Xlite from the Grandstrea, the Xlite ends up using the
ulaw codec as does the Grandstream

Why the asymmetrical behaviour?
Why does the Xlite accept a non-GSM call when it is set to do GSM?

Thanks for any help.

Rob

Actually it is worse than that.

Whatever codec I choose in Xlite, when calling the Grandstream it always
uses the GSM codec even if it is greyed out.

[Asterisk-Users] Soft phone sound quality help

2005-01-27 Thread Rob Scott
Anyone got any tips on improving sound quality on soft phones running
under Window XP SP2?
I have tried Xlite, SJPhone and Firefly.
They all seem to have significant sound quality problems. We have a
reasonable sized network of several hundred devices connected together
using Layer 2 switches, i.e. pretty dumb switches with no QoS.
I also have a Grandstream connected to the same switching gear.

The Grandstream sounds pretty good with very few drop outs or sound
problems on ulaw.
The soft phones all have problems although they get less when going to a
lower bandwidth codec, but then lower bandwidth gives you worse sound
quality too.

Is there any way I can improve sound quality on the softphones?
Or it is pretty well the general rule that they have poor sound quality?

It makes sense to install a softphone on each of the 200 desktops we
have but not to buy 200 Grandstreams or equivalent, and not to upgrade
all our network switches.

On the Asterisk side, jitter buffer is turned on with default settings.
TOS is turned on for SIP although I doubt the switches can do anything
with it.
I have played around with a lot of Asterisk settings but without getting
good results.

Hi,

I think you didn't set usecallerid=yes in your zapata.conf? 
Another way is to set the callerid in your extensions.conf via exten = 
807440,2,SetCIDNum(0${CALLERIDNUM}). So you also have a 0 in front of the 
displayed number - nice for callback.

regards
Jens

 Hello,
 
 I've added a ZAPHFC card to my CAPI based system. Calls coming in via 
 ZAPHFC do not forward the caller id to the SIP phones. Calls coming in 
 via CAPI do forward the caller id to the SIP phones.

[Asterisk-Users] Poor sound quality on ISDN BRI calls

2005-01-20 Thread Rob Scott
I've been struggling with connection Asterisk to ISDN BRI lines for a
while.
I have it working with the latest bristuff and compatible Asterisk
version:

 Asterisk 1.0.3-BRIstuffed-0.2.0-RC3a

I am using a cheap Centronics ISDN card and the zaphfc drivers.

It works but users complain that the sound quality is not good.
They have Xlite phones on their desktops.
Xlite to Xlite through Asterisk is fine.
Xlite to PSTN through ISDN is not good.

Anyone got any experience with this kind of setup and improving sound
quality?

[Asterisk-Users] Sound quality poor everywhichway

2005-01-20 Thread Rob Scott
I am hoping someone is going to bite on the sound quality issue.

I have Asterisk connected via a Conceptronics HFC-S card to an Elmeg
ICT880 PBX internal extension line. Running Asterisk 1.0.3 and latest
Bristuff.
I have firefly and Xlite clients running on Windows XP.

Calls between Xlites through Asterisk seem to be fine.
Calls from anything to ISDN is terrible whatever settings I change.
Calls on VoiP for example to the 411 service on FWD through my Asterisk
box are not as good as using the same service by phone, not by a long
way. There is distortion and also a kind of harmonic tone in the
background when the person is talking on the other end (i.e. it sound
like someone is playing a low toned kazoo in time to the person
talking).

Everything is going ulaw.
It is on a quiet network.

The Desktop is an IBM ThinkCenter with built in audio - 2.66 GHz P4.

Anyone got any ideas?
I am pulling my hair out here trying to get this working.

[Asterisk-Users] Is an unregistered phone busy?

2005-01-18 Thread Rob Scott
Asterisk seems to regard an unregistered phone to be busy.
Is that correct? Is not an unregistered phone unavailable?

It is odd to me that if someone dials an unregistered extension, then
the dialplan jumps to busy and voicemail kicks in saying that the person
is on the phone, when clearly they can't be if the phone hasn't
registered.

Any way around this?

[Asterisk-Users] Sounds cut out problem - HFC-S card, zaphfc, Xlite

2005-01-11 Thread Rob Scott
Hello Asteriskians!

I have an Asterisk box with a simple HFC card in it and a bunch of
people using the Xlite software to connect. The HFC card is connected to
an internal extension on our legacy PBX.

So far so good. The Xlite clients can call each other, and the internal
extensions on the PBX and the Xlites can call each other, no problem.

The problem is when using an Xlite to dial an external number through
the legacy PBX.
What seems to happen is that there is some kind of noise suppression so
that unless the remote party is speaking very loudly the sound cuts out.

Now, I don't know if it is the ISDN connection, Asterisk or the Xlite
client that is causing the problem. I've tried different settings on
everything I can think of and trawled the web for days but so far
nothing useful. I've turned off silence suppression on all the Xlites.
I've turned up the rxgain on the ISDN channel in case it is too quiet. 

Nothing so far has helped.

Calling directly through the PBX from a normal extension phone doesn't
seem to have any problems.

Anyone have any idea what I should look at?

Thanks

[Asterisk-Users] Problems with Devkit Lite setup

2003-10-10 Thread Rob Scott
At one point I did have this kit working but since upgrading to the latest
Asterisk, it no longer seems to.

I had the following problems after several reinstallations:

   - USB adaptor had a proper dialtone, asterisk recognised the pickup,
but pressing keys on the handset had no effect

   - USB adaptor produced a strange horrible tone, not a dialtone;
pressing keys has no effect

   - USB adaptor silent; pickup not recognised by Asterisk

So you can see my situtation has gradually deteriorated with each 
tinkering/CVS-reinstall of the system.

What I don't understand is what Linux or other elements do I need to get
the USB adaptor to work?

I am running RedHat 9 with the 2.4.20-20.9 kernel.

Apart from these problems, I also noticed the following when using the USB
adaptor:

   - unplugging and plugging the handset into the line side of the adaptor
killed the adaptor; have to restart the machine to clear the problem.

   - unplugging the USB adaptor from the USB port causes all manner of
problems. 'rmmod'-ing and 'insmod'-ing astrisk related modules doesn't
help. Running asterisk or 'ztcfg' always complains of problems on the USB
adaptor channel. Restart of machine needed.

   - sometimes problems with the computer's audio system

Subject: [Asterisk-Users] RE:911, networks of * servers, etc. (was: VOIP

Yes, I'm familiar with the E911 platforms and their requirements to 
some degree.  The trick is that the people running Asterisk PBX 
systems have no visibility into SS7, and that is an unreasonable 
expectation, so some other out-of-band method for moving caller 
location to the PSAP is required.

As far as geographic location tracking is concerned: that is the 
user's problem.  If they don't have the correct information in their 
device, then they're SOL.  There is _no way_ to develop lat/lon/alt 
coordinates from an IP address, despite what any .com 
flash-in-the-pan company says they can do with their clever 
databases.  Thus, the PBX/switch provider will have to enforce their 
own database of device-to-geographic-coordinates.  (As mentioned, 
maybe a SIP header is a reasonable thing to use for the UA to relay 
this data to the proxy.)  I am not concerned so much about the 
ability of the devices to send their data to the proxy: I am VERY 
concerned about how the proxy then looks up the appropriate PSAP, and 
then relays the data for the call to that PSAP.

JT




911 through the phone system is tricky business. e911 which is the 
automated process of handing the address to the 911 center uses the SS7

database to do it's work (the database is created when the LEC runs 
physical lines to locations not by people filling anything out). Cell 
phone service providers have the simuliar problems as VoIP service 
providers are facing are realizing with call forwarding and call 
following it will get worse.. Congress has mandated that the cell phone

industry make it possible to track a cell phone users within 300yards 
via cell sites and triangulation. By 2005 every cell phone will be 
required to have a GPS and send GPS information to the 911 system when 
they call 911. If you want more information on e911 try 
http://www.fcc.gov/911/enhanced/ . As the cell phone industry grows 
there will be a need for a national 911 call routing center. I bet it 
won't be free.

Dialtone?)



OK, that VOIP dialtone? thread was getting really out of hand, so 
I'll condense my answers into one big ugly message:


1) 911 service.  Yes, that is one of three reasons to keep your PSTN
line.  The other two reasons are:   Inbound calls from local callers
still should work on a POTS line, for now.  You can't find VOIP 
providers in most area codes, so you'll most likely need to have a 
local number that finds it's way to you for local tasks. Secondly, 
the Internet is not as reliable as the phone system. Sorry, folks, it 
just works that way right now despite what your network engineer might 
tell you.  That's not to say it's unreliable, but those last two nines 
are very expensive... Besides, any good network engineer will tell you 
that you should have multiple paths for your IP connectivity.  With few

exceptions, most homes do not have multipath connectivity.  (note: 
businesses may in fact have better uptime on their IP network than 
their phone network, if they have competent engineers and a reasonable 
budget.)

1.5) There are reasonable technical solutions to this problem, but for 
the life of me I can't figure out why the 911 centers haven't gotten 
their act together and solved this.  There are two halves to this 
problem: What PSAP do I call? (and what phone number)  and How do I 
get my location data to the PSAP once I call them? C'mon, this is not 
difficult.  The first question can be answered
trivially: there _must_ be a database of address-to-PSAP mappings. Any 
PBX administrator (or SIP phone owner, for that matter) should be able 
to figure out their address.  Methods for associating the PSAP number 
with the phone are numerous, and trivially implemented - if people 
don't keep their address information updated, they're SOL (though you 
can remind them in an automated fashion to keep it updated - just 
forbid them from using the service unless they verify the address every

month or so.)

The second question is more difficult, but certainly possible.  There 
may be kludge ways of doing it, and there should be more elegant ways 
of doing it.  A SIP header with lat/lon/alt data that gets sent from 
the UA only on 911 (or other programmable string) calls might be 
reasonably elegant... maybe.  But that only gets the data to the SIP 
proxy.  That doesn't solve the issue of how you get that data from the 
SIP proxy to the PSAP, which at some point will be almost certainly 
through a PSTN connection... ADSI FSK, maybe?  Ugly, and PSAPs would 
not want to invest in equipment.  A national
