Ceteris paribus, I prefer IAX. It tends to "just work" and it has a lot 
fewer "knobs" to turn.

Some say the audio quality is better with SIP. My experience has been with 
"low volume" (xx) calls across the internet and "high volume" (xxx) within 
the same cabinet.

I'd try IAX since it is so simple to configure. If you are not satisfied, 
try SIP.
