Installed a Ip extension on a SL1100, programmed the phone at the remote site, sip settings, NAT trans,dynamic,WAN ip of the router at the KSU side and the phone comes up fine. After 2 1/2 minutes the phone resets and displays server connection lost. After it reconnects works fine again for 2 1/2 minutes then it resets again, like clockwork. What would cause the phone to keep resetting every 2 1/2 minutes. The VPN is managed by the ISP and all port forwarding is controlled by them. I instructed them yo forward 5080 & 5081 to the daughter board ip and 10020- 10083 to the ip assigned for voice.
