include your sip.conf entry for both fwd and your phone.
By: tan (tan) 2003-11-27 02:29:33.000-0600

We have seen codec negotiation problems as well:
endpoint: set to only negotiate g729 as in sip debug extract below:

c=IN IP4 81.86.185.223
t=0 0
m=audio 35034 RTP/AVP 18
a=rtpmap:18 G729/8000
a=ptime:20

Asterisk offers it's list:
a=rtpmap:8 PCMA/8000
a=rtpmap:0 PCMU/8000
a=rtpmap:18 G729/8000
a=rtpmap:97 iLBC/8000
a=rtpmap:3 GSM/8000

What gets negotiated is alaw, although endpoint hasn't even advertised it. A show channels shows:
NativeFormat: 8
WriteFormat: 2
ReadFormat: 8

sip.conf shows:
disallow=all
allow=alaw
allow=ulaw
allow=g729

If allow=g729 is placed after disallow=all then g729 is negotiated. There seems to be a problem here.
By: Brian West (bkw918) 2003-11-28 10:31:39.000-0600

Its FWD thats doing this.  I have the same issue with their 411 number.  Its like it wants to speak g729 if its offered no matter the priority.
By: Thorsten Lockert (tholo) 2003-11-28 10:38:35.000-0600

But I don't offer G.729A on my system -- I do not have the codec installed, and in my sip.conf I have:

[general]
tos=lowdelay

disallow = all
allow = gsm
allow = ilbc
allow = speex
allow = ulaw
allow = alaw

register => 25685:XXXXX@fwd.pulver.com

Free World Dailup is more or less standardized on G.711 according to Jeff Pulver.
By: oliver (oliver) 2003-12-01 10:15:06.000-0600

I'm seeing the exact same problem with FWD and have been in contact with one of their techies about it.  They're using a Cisco-gateway for their US toll-free access and it's configured to prefer G.729, but according to them, it should allow GSM and G.711 as well.  I suggested that they might want to try setting G.711 as the preferred CODEC, but am still waiting for an answer.

Here's the relevant part of my config:

[fwd.pulver.com]
type=friend
callerid="Free World Dialup" <>
canreinvite=no
fromdomain=fwd.pulver.com
host=fwd.pulver.com
disallow=all
disallow=g729
allow=ulaw


As you can see, I've even explicitly disabled G.729, although I doubt that would make any difference.  I've also tried allowing all but G.729, but it didn't change anything.  I'm running the latest CVS-version of Asterisk (CVS-12/01/03-16:53:18)



  Grtz,

     Oliver
By: Brian West (bkw918) 2003-12-14 11:41:33.000-0600

Can anyone confirm this has or hasn't been fixed?
By: oliver (oliver) 2003-12-14 14:33:37.000-0600

I can confirm the problem is still present in current CVS.
By: Brian West (bkw918) 2004-01-07 00:07:50.000-0600

Is this a problem with just FWD or does it happen else where because I can't get this to happen.
By: jrollyson (jrollyson) 2004-01-14 03:40:57.000-0600

I believe this related to FWD forcing g729 for a short period of time, and is no longer an issue, and never was a bug.
By: Thorsten Lockert (tholo) 2004-01-14 12:54:52.000-0600

Sorry -- this is still happening with my 7960 phones and Asterisk.  I do see some odd behaviour demending on how I try to limit codec selections in sip.conf, too...  If I only allow ulaw & alaw to FWD, I get an "unable to transcode G729A to ULAW" message (it appears that G729A gets negotiated on the 7960 end of things!!), if I also allow GSM or ILBC on the FWD end (!) it works, but with some warnings about frame types.  I do get audio working, however(!)

Here is debug output when only uLaw & aLaw is enabled for FWD:

By: Brian West (bkw918) 2004-01-15 16:26:28.000-0600

set the preferred code on the 7960 to ulaw or alaw and it will stop doing this.  What firware are you running on the 7960.
By: skornn (skornn) 2004-01-19 08:49:04.000-0600

I also have the same issue, using x-pro software. Using allow=g729 before other codecs in sip.conf allows it to work, but when checking voicemail or echo test * doesn't work. * warns it is unable to forward frame and cannot find path to codecs.

is this still a problem ?
