[Asterisk-Users] IAX2 trunk mode not working

[Javier Pinzon]

Hi all - We have several servers working just fine with IAX2 w/o trunk mode.

 

We are trying to setup trunk mode to save bandwidth, but we can not achieve
the savings with our current configuration (see below).

 

When we place a call between * boxes A & B it works fine, but the command
'iax2 trunk debug' shows no activity for the trunk mode (1 peer, 0 calls).

 

Anyone who has been able to configure IAX2 trunks can help?

 

Server A is a Dual Xeon 2.8 Ghz running a CVS from 2/16/04 on Redhat 9.0

Server B is a Pentium III 900 MHz running a CVS from 8/25/04 on Redhat 9.0

 

Both servers have G729 installed and working. Here is a pseudo-diagram/flow:

 

PSTN ---{PRI/TE410P}--->  Server A ---{IAX2}---> Server B ---> Music On Hold

 

The connection between A & B is a 128Kbps dedicated IP channel and we expect
to be able to handle up to 10 calls. Right now 5 calls is the limit with
G729. After that the voice is choppy.

 

Thanks

 

Javier
