It wasn't the same magnitude (more like 4 seconds for me), but I had an
issue where the default eyeBeam (the commercial version of X-Lite) install
was imposing a delay when a call first came in while it attempted to contact
a non-existent STUN server.  When I removed the STUN server setting, call
setup was immediate.

Might be worth looking at.  Have you done a trace on the PC where the
softphone is running (without a filter) to see what network packets are
flying at the time the call setup happens?
