Is it possible to configure LCR between two CME sites? I have two different CME's that are in two different states and would like to take advantage of the PSTN connections at both sites. I'm currently using h323 dial-peers for 4-digit dialing and toll bypass, but am not quite sure how to get site A to dial out site B's ISDN line for PSTN calls.
This can be done. Make the configuration transparent to the IP phone users, so they will just dial the numbers as long distance numbers. Configure redundancy via dial-peers. Two dial-peers will do the trick. The first dial-peer will send the call to the remote gateway for it to be routed out as a local call. If the number dialed is dialed as 91+10 digits, strip the 91 (and the area code if necessary) before sending the call to the remote gateway which should already be configured to route the call out as a local call. The second dial-peer is a failover dial-peer, to be used incase the WAN is down or the remote gateway is not available to route out the call. In this case, the call is sent out the local gateway as a normal long distance call.
