[Freeswitch-users] Proxy Media for IVR bridged calls

[David Ponzone]

Rogelio,

proxy-media is not required for G729 passthrough.
By default, FS does relay media, and G729, among others, is available  
as a passthrough pseudo-codec.
Proxy-media tells it to be a little bit more transparent, so you can  
use codecs that FS does not handle at all, or you can relay T38.

In your case, I think your issue is a codec negotiation one.
If a call from the outside hits your IVR, perhaps G711 is negotiated  
(that depends on the order of the codecs proposed by your carrier).
And if you are using the default IVR sound files, I am pretty sure it  
was G729, because if not, you wouldn't be able to hear anything.

Then, if you bridge to a G729 phone, you are asking FS to transcode  
between leg A, which was G711 and leg B which is G729.

What you have to do is:
-force leg A to be G729
-convert all your IVR sound files to G729, make sure FS loads  
mod_native_file and in your IVR config, reference all sound files  
without their extension
