asterisk users - Jan 2006 - ILBC to G711 transcoding experince ?

Hello All,

Anyone here has experience of accepting a ilbc call and sending it on g711 or
g729

I am having problem in VOICE , call goes though but there is no voice.


Senario:

Call is coming in from Machine A to Machine B, sending to Machine C

Machine B is an asterisk box, transcoding it from IBLC to G711 and g729.


Problem:
Voice is not appearing on the sip user sitting on machine A

Already tested:
Xpro Logged in on Machine B using ILBC  sending to Machine C and it works fine.

Do send me your charges.


Thank You,

Rehan

it shouldnt be a problem from ILBC to g711u/a , but for g729 you need
a licence, otherwise no transcoding can ocurr. However does not seems
to be your problem, since the call should be hanged up, and you just
dont receive audio. That seems to me more like a problem with RTP not
finding a right route to the final UA. Can you be a little more
specific about where are located machines A,B,C. Firewalls, etc?

regards

Thank You for replying.

There is some progress, and confusion, so i posted the 2nd post about it.

Here is what is happening.

When call comes from Machine A to Machine B, and Machine B is running asterisk 
1.0.9 the voice on ilbc is fine, i played mp3 on it.

But when the asterisk on machine B is 1.2.x there is no voice on machine a
coming
from machine B.

I was able to send the call using 1.0.9 to machine C however, the problem now is
that
the call going to machine C has incorrect user name

It should be username@ip its going as asterisk@ip using 1.0.9

With 1.2 user name is going correctly


There are no firewalls or other issue so far.

It seems like an RTP issue, but i don't know what to fix.

My msn is rehan@rehan.com if we can continue there.
