I have CM 4.2(3) and need to setup a SIP trunk to a voip provider, I have the following info from them:
SIP Registrar: xxxxx
SIP Domain: xxxxxx
but from what I found out SIP trunk in CM 4.2 won't support authentication. So I think I need a gateway.....I would have to create a SIP dial peer on the gateway and forward the traffic from my CM to it via the trunk. The dial peer would handle authentication...
is this correct?
