I have this environment:
IP Communicator 2.1.3
Video Advantage 22.214.171.124
CME 4.1 running on Cisco2851 with IOS 12.4(15)T
I have an Easy VPN running between Cisco2851 (Server) and Cisco857 (Remote).
The IPC can register and work normally while Video Advantage is not running.
Once I start VA, the phone unregister and tried about every 50 seconds to register again but unsucessfully.
The same PC running VPN client 5.0.02.0090 can connect succesfully with voice and video if I use VPN Client instead of Easy VPN Remote.
I think something in 857 config should be adjusted but I need some tips to identify and troubleshoot the problem.
Thanks in advance
