Getting avaya ip office v2 to work with grandstream fxo gwx4104 as a sip trunk

[varrin]

Hi all,


I want to get an avaya pbx ip office 500 V2 to make outgoing and receive calls to an extension programmed in the pbx using a grand stream fxo gwx4104.
Does anyone know what I need to program in the pbx for it it work with fxo gateway.
I want to set it up as a sip trunk
So the gateway has an ip i.e 192.168.42.50 and pbx is 192.168.42.1.
I have a sip trunk license allready, but don't know what to fill in for the new sip trunk in the pbx

thank you in advance

Add the SIP trunk in the "Lines" section. Enter the far-end IP, port, protocol, etc. Settings should match on the other side.

Hi mlombardi1,

Do I add the IP of the fxo gateway in ITSP domain name and also in the ITSP Proxy address?
Also the port used by the gateway is 80 if not mistaken, I should enter in the Send port correct,
And do I enter the Username etc of the gateway also in the sip credentials and leave Call routing Method on Request URI and Association Method By Source IP address?
