There is no audio in audio conference

[enio.eltz]

Hi

I could install My Teamwork in a vmware and connect it with my OXO.
I created the SIP trunk from OXO to My Teamwork (6000, 6001, 6002 and 6003 are the numbers in OXO that call conference center with their own languages). I can call from any OXO set to those numbers succesfully, I listen to language prompts succesfully.
I can open user web interface, log in, use IM, apllication sharing, etc.
The problems are:

I call 6000 (Portuguese prompt) from the OXO set, and dial the conference code. When my co-worker calls 6000 and dials the same conference code, sometimes we talk to each other for a few seconds, after this there is no audio. sometimes, always there is no audio.
when I call an user with web interface user, the same happens.

There are traces available. Any help is useful.

Thanks.

Codecs Enio, check codecs

Hi Cavagnaro

Yes, I checked them. Teamwork is configured as G729 for first option. In OXO, it is predefined, G729, right?
As I wrote, I start a call with user web interface, we can talk to each other for 5 seconds, a little time, in my understanding codecs should be right.

Thanks.

Nop, you didn't say that... check it
Well if you do have audio sometimes then...maybe RTP packets lost? Same VLAN? Same network segment?
Have you done a TCPDump (Wireshark) and see why the call drops? The disconnect message and reason must be there
