I am looking to put in a Cisco VOIP system in a small office (along with CME and Unity Express). Everything makes sense, but I am a little unclear on one basic thing ...
I have a 2811 that will be a gateway between the PSTN and the Cisco CME system. It is my understanding that when inbound calls come in from the PSTN matching a pattern, they are sent to the CME system like so:
dial-peer voice 10 voip
session target ipv4:10.1.1.2
with 10.1.1.2 as the CME system (a 3800 series router).
But what about outbound calls to the rest of the world? In other words, how do I configure the 2811 to route outbound calls over the trunk line (FXO port) to the PSTN?
