[Asterisk-Users] AArgh, * and the 7960

[Iain Stevenson]

I have ethereal installed and I'll do a full call trace.  The Catch 22 is I 
don't have access to access to a source of repeatable (ie recorded) content 
accessed through IAX.  That would help in producing traces for the ATA and 
7960 for comparison.  I mainly use IAX for non-critical international 
business calls to people who wouldn't want to be * testers.
