[Asterisk-Users] High latency from Europe, 500-800ms.

[Paul Cheng]

You are right to suspect codec issues here. What codec are you using at 
the various endpoints?

Make sure that the Asterisk box is set up with the correct codecs in 
the conf files, otherwise it will try to transcode and this will often 
cause bad audio quality like you mentioned. If you're using G729, make 
sure that you don't have any rTt or other options in dial enabled, 
otherwise, Asterisk will proxy the media.

I've read in previous threads that the jitter buffer is broken in iax 
and we tried with and without and it was much better without.
