Here's my topology:
GW1: is at branch 1 and has a Local PRI circuit ONLY
GW2: is at branch 2 and has a Long Distance PRI circuit and some local PRI's
If users at branch 1 want to make long distance calls, they must use the long distance circuit at branch 2. That's what I wanted to accomplish. I can configure a voip dial-peer on GW1 to send long distance calls to GW2. Do I need to do anything extra on GW2 to make it work? Note, everything on GW2 has been working fine today.
