I have run into this same problem using the softphone and Cisco VPN client. The problem is that during the RTP setup, the softphone registers it's IP address as the first IP address it finds on the PC, which is the IP address on the local network, not the IP address of the VPN interface. And of course, the other device cannot route to that address.
In the Softphone, under settings, you can manually set the IP address to use. It's on the Audio tab, under Netrok Audio Settings. You can specify the address from a dropdown list of addresses, but that gets reset when the VPN connection is lost. The best way to do it is to place the file getIP.asp on a internal webserver and then specify that URL on the Automatic selection option. The getIP.asp simply returns the source IP address the client when queried. I beleive this file can be found in the install files for the softphone.
