IP communicator phone across VPN is on separate subnet
I am using Cisco IP Communicator across a VPN. The address assigned to the software phone is 192.168.100.X. The phones on the main network are on the 192.168.11.X network.
The Cisco Call Manager is on a 192.168.1.X network. I can ping back and forth between the 192.168.1.X and 192.168.100.X networks across the VPN. But cannot ping the 192.168.11.X network from across the VPN.
