The 'port' setting for a peer has nothing at all to do with where 
Asterisk would listen for traffic; it defines the port number Asterisk 
should *send* traffic to for a non-dynamic peer.

You didn't mention which version of Asterisk you are using, so it's hard 
to give you concrete answers. All current versions of Asterisk can only 
listen on one port for SIP over UDP traffic, but the versions that 
support SIP over TCP can listen on a different port for TCP. If you are 
using a TCP-capable version of Asterisk and a TCP-capable endpoint, you 
can try that.
