Depending on your client, you can also go through A VPN. This could be done from an iPhone or android phone for example. Guillermo Sent from my iPhone

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.
