Asterisk to Asterisk using SIP


I’m trying to connect two asterisk boxes using SIP as there is a firewall between the the two.

One is setup as an IP PBX and the other as a gateway, what is the best way to do this?

Use IAX see here … al+servers

theres a very strict firewall in the way and sip in the only protocol, i`m sure is open.

Its a uni project and i need to connect to a server i have outside of the firewall.

I will give it a go but i dought it will work.

SIP methods are also specified here … al+servers

Yeah spotted them earlyer, cheers for the help!

Ok, I were very interested when I saw the title of that post but is there a solution without using IAX ?
