Summary:                    Codec options in gtalk.conf not respected
Description: 
When you have in gtalk.conf the following configuration:
[buddy]
disallow=all
allow=gsm
...

The gtalk connection is established even if the gtalk client do not
support the GSM codec, and the connection/channel appears established with
a different codec that it is not allowed (like for example the slin
codec).

On the other side, a similar configuration with IAX works as it is
supposed to.
When I have a configuration like this on my iax.conf :
disallow=all
allow=gsm
...

And when my remote client do not have GSM as one of the possible codecs,
the connect attempt is rejected and I receive the following message in my
zoiper iax client : “bearercapability notavail”

And on the asterisk server side I have the following message:
[Aug 30 11:40:50] NOTICE[1358]: chan_iax2.c:7645 socket_process: Rejected
connect attempt from XX.XX.XX.XX, requested/capability 0x200/0x60c
incompatible with our capability 0xe002.

Isn’t it suppose to work the same way with the gtalk ?

Testing components:
- Fedora core 3 + Asterisk server 1.4.11 (no zaptel, no libpri) + iksemel
1.3
- Google Talk client 1.0.0.104
- With the following patchs applied:
http://bugs.digium.com/view.php?id=10509 
http://bugs.digium.com/view.php?id=10548 (branch-1.4-10548-3.diff)

Thank you for your answers.

Initially I was placing the call: IAX -> Asterisk -> Gtalk
But now I tried in both directions and have the same results.
I have restricted my tests to gsm only (gtalk.conf: disallow=all
allow=gsm)
The gtalk.conf configs are not respected. (gtalk show channels always
indicated that the codec being used is slin)

Please find bellow the debug information you requested. I have done a full
search and replace of certain parameters just to avoid having some
information posted here at a public place, but if you prefer to have the
original data, I may send you through a more private channel. (email?)

I have tried with no active firewalls on both sides (server and clients)
and I have also configured additional rtp ports in rtp.conf ->from 1650 to
53000. Initially it was only from 1650 to 4650 but it seemed from the debug
that now higher ports are being used.
But the audio still doesn't work from the gtalk client to the iax. (but ok
from iax to gtalk).
I have also seen the connection monitor on the gtalk client and there are
only received Bytes (recvB), no sent Bytes (sentB = 0).
In the asterisk debug output it seems there are also only rtp packets from
asterisk to the gtalk client (confirmed with a iptables logging)

Really strange this one way audio problem...
Is it just a simple thing I'm not seeing? :-)

Asterisk debug output :
(note: for these tests I sticked with the 1.4.12 + this new patch)
