Asterisk is highly multi-threaded and definitely takes advantage of multiple
cores.

There are a few places where concurrency could be further improved, but its
really quite good in 1.4.  (IAX in 1.4 does handle traffic using a thread
pool so will take advantage of multiple cores).

By the way, I have a client with a four-core Xeon box doing SIP to IAX
conversion - that box can handle 1000 concurrent calls.
