asterisk users - Nov 2014 - One way audio internal

Hi All

 

We have a strange issue with our hosted asterisk server running on Debian

Internal calls btween extensions using g729 give one way audio

As soon as we change the codec to ALAW the issues goes away.

 

Any ideas how to fix this?

Outbound calls via a trunk work fine with g729

 

Kind Regards

Unless you have serious bandwidth issues, just forget about g.729 and change 
to a-law throughout.  A-law is what the PSTN  (in civilised countries)  uses 
anyway, so you won't need to transcode  (which chews up processor resources 
and risks compromising quality)  for calls to and from the outside world.  

If you really need to use g.729 and are outside the USA  (therefore, beyond 
the reach of software patents),  there is a free version that you can use -- 
and this one, better than Digium's offering, comes with the Source Code so
you
can be sure it isn't doing anything nasty behind the scenes.

But to be honest, you probably are better off just sticking with a-law.
