We are implimenting a CallManager with 4 remote sites that are connected via PtP ATM DSL Bonded Connections. I am having a problem with getting the MGCP Gateways to register, here is the reason why...
The CallManager and Unity Server are on a 10.128.0.0/28 subnet, the remote sites are all on a 10.132.0.0/26 subnet. The PtP links between the routers at the remote sites and the 7206VXR router at the core are in the 10.0.0.0/30 subnet. Because of the way that the provider's network is setup, the servers in the 10.128.0.0 network CAN NOT communicate with the 10.0.0.0 transit network.
When I configure the gateways at the remote sites with the IP Address of the CallManager server, the gateway tries to contact the CallManager going out the ATM interface with the 10.0.0.X address, which is not accessible to the CallManager.
Is there a way to pick which source address the MGCP service uses?
