Upgrade firmware from V1.1.14 to V1.2.11. This router was used to pass VOIP calls (using port forwarding for signaling and RTP)from private to public side of the router in a isolated test lab. Configuration prior to upgrade was recorded and then verified after the upgrade. All went well until I tried to pass calls through the router, seems the RTP will not go from Public to Private even though I have all required ports being forwarded to the endpoint (private side). I have even diabled the firewall radial button with not luck. Any help would be gratefully appreciated. Thanks in advance. Bob
