[Asterisk-Users] Windows IAX soft phone

[Eric Wieling]

SIP negotiates the port numbers it will use for voice for each call. 
The call setup is done via port 5060 but the voice packets use
dynamically allocated ports and so firewalls don't know what ports to
deal with when doing NAT.  IAX does NOT negotiate the port numbers for
the voice stream, it always uses the same port number.
