oice provider is upgrading SBC. They are changing the port from 5060 to 5090. The IP phones connect to the Adtran 908e using port 5060 and need to communicate to SBC on port 5090. This is a sip proxy registration. Is it possible to have the Adtran make this port change?
Yes.
Syntax:
sip proxy sip-server primary sbc.example.com udp 5090
for hostname (must have working DNS) or
sip proxy sip-server primary 192.168.1.1 udp 5090
for IPv4, or
sip proxy sip-server primary 1001:db8:1::1 udp 5090
for IPv6
