[Asterisk-Users] Problem with chan_iax.c implimentation causes bad audio?

[Matt]

Interesting.   I mean I'm sure this vendor HAS an issue with IAX... 
but I guess I'm just curious what brought it out and if it's an issue
with his implimentation of asterisk.  At any rate.. it is odd that I
only have IAX issues to him and not someone else.  Of course, I (and
the other company) are both running asterisk 1.0.9 ish.  So perhaps
the IAX issue is only recent in 1.1--> ?
