[Asterisk-Users] IAX experiment - Should this have worked better?

[Chris Albertson]

Should this have worked better?

1) I register my * server with iaxtel.com as user2:blah at iaxtel.com
2) I call to my * server using X-Lite from a Win2k box and dail
   the 1700 iax number associated with user2 above
3) my * server corectly routes the call thru   
   _91700NXXXXXX,1,Dial(IAX2/${IAXINFO}@iaxtel.com/${EXTEN:1}@iaxtel)
4) sure enough I here the main menu from my own * server.
   It seems to have worked but...

The throuble is the __very poor__ sound quality. It has long gaps of
missing speech, some jittery speech and then it disconnects.  I know
the
sound is making a round trip to iaxtel.com andback and then oover
a local SIP link back to X-Lite but but the result should, I think be
understandable.

I am also sending 800 numbers to iaxtel,com. with this: 
_91700NXXXXXX,1,Dial(IAX2/${IAX...
and the sound quality is not that bad, not perfect but but "fair"
and certanly without dropouts or gaps.

So what's up does two hops over IAX kill the audio?  Should I
messaround more with jitter buffer settings?

I'm on a DSL line, in back of a Linsys router/firewal
My 2.6Ghz P4 nerver shows more than 1% CPU utilization
