Trust me on this one - you *really* want to take the time to install 
Etheral with the plugin. It makes debugging problems like this much 
easier - you'll be able to see whether the client sees the packet, 
whether it sends a response, if there's version skew causing INVALID 
packets to be sent for certain challenge/responses, etc.

I'd only stick trace code in the iax-client library when you've sniffed 
what's going on so you know where to add it. :)

iaxclient/lib/libiax2/src/iax.c is probably where you'd want to look. 
Which functions depends on what's happening. iax_do_event() might be 
relevant for outbound packets, for example. You'll have to delve.
