[asterisk-users] Asymmetric codecs in IAX2 trunk

[Magdy Salama]

I'm trying to implement the following setup:


Internet ---RTP--->Asterisk1----IAX-trunk-over-VPN---->Astrisk2---->PSTN


The outbound bandwidth at asterisk2 (PSTN) is limited and expensive, so 
I want to keep it low as possible. I want to use Speex VBR for the 
outbound stream and keep the inbound stream at G.711 in the IAX2 trunk. 
Speex streem will be transcoded to G.711 at Astreisk2.


My question is: Does IAX2 trunk support asymmetric codecs (different 
codec at each direction)?


regards,
