Hello,
We cant get the NortelĀ“s "Multimedia PC Client" to operate over a Cisco VPN Client. The Nortel client seems to find the SIP gateway but it is not able to get any call connected. We are using the Multimedia client 3.0.416 and a Cisco VPN client 4.8.00.0440. The Nortel client works fine when it operates via a non ipsec wireless or LAN connection.
