asterisk users - Jul 2008 - Codec negotiation for Thomson ST2030 and g729

Hi all,

i'm trouble with codec setup on an asterisk machine 1.4.18 and some
Thomson ST2030 as extensions.

In the users.conf file for internal extension i have:

disallow=all
allow=g729
allow=alaw
allow=ulaw

Without any codec installed (i mean with original g729 of asterisk)
all go fine, calling from an extension to one other:

Peer             User/ANR    Call ID      Seq (Tx/Rx)  Format
 Hold     Last Message
10.9.9.9         202         11a6323d2ff  00102/00000  0x100 (g729)
 No       Tx: ACK
10.9.9.10        201         a8749-c0a80  00101/00001  0x100 (g729)
 No       Rx: ACK


Installing the open source binary of g279 (codec_g729.so in modules
dir) and restarting asterisk, the same call require transcoding:

Peer             User/ANR    Call ID      Seq (Tx/Rx)  Format
 Hold     Last Message
10.9.9.9         202         1992c2d149e  00102/00000  0x8 (alaw)
 No       Tx: ACK
10.9.9.10        201         140a6d-c0a8  00101/00001  0x100 (g729)
 No       Rx: ACK

The CALLED extension uses alaw instead of g729.

This uses a lot of CPU (up to 10% in my P3 machine).

Where is the trouble? Asterisk bug? Thomson do not recognize g729 GPL
as standard g729? I must set the framebuffer size?

If i set ONLY g729 as allowed codec all go fine: all calls uses the g729 codec.

Why codec negotian in the allow= list is not respected? Depends on
codec binary? It's strange...


Thanks to all...

If my memory serves me right, we could use Thomson ST2030 and Asterisk 1.4.
Have you tried with another soft or hardphone  ?
