hi,
When I load X-Lite behind a Single Mapped Port Symmetric NAT Firewall and make a call to it, the X-Lite rings and I can hear voice in both directions. The problem is when I leave the X-Lite sitting idle for over 1 minute, the inbound calls to client start to time out. Outbound calls from client work no problem. Im not receiving anything on the X-Lite debugs, and when i debug the SER, I see repeatedly sending Invites with no response. Below is the debug...64.72.107.2 is my Gateway, .4 is my SER, and .1 is my firewall NAT address where my client X-Lite sits behind. If i close the X-Lite and open it back up, I am able to make calls to it again until I leave it sit idle...Any ideas? Could something be wrong with my nathelper?
Failed Attempt...
