Besides changing to a non standard port (ie. not using 5060), you could also try to use TLS transport instead of UDP. If signaling traffic is encrypted, it has a better chance of punching through any firewall.
That depends on how it's being blocked. If it's being blocked crudely, on a port level, then they'll just block SIP-TLS (5061) too. If it's being blocked by DPI that identifies the packets as SIP, then switching the utilised ports won't work, and, in fact, encryption and/or tunneling is the only way around it at all. -- Alex Balashov - Principal Evariste Systems LLC 235 E Ponce de Leon Ave Suite 106 Decatur, GA 30030 United States Tel: +1-678-954-0670 Web: http://www.evaristesys.com/, http://www.alexbalashov.com/
