Hello,
I am having issue get my ISSABEL sip trunk with Congstar.de working. I capture the traffic on my router of the trunk working using Fritzbox. In this capture file below 217.254.36.126 was my external IP.
Noth the Issabel server and Fritzbox have a private IP address and are behind the same NATted external address.
I am looking for an Issabel configuration that would mimic the same behaviour as that of the Fritzbox. Currently I can register and make an outgoing call with Issabel but incoming doesn't work. The ITSP try to connect to the external address on port 5060 which off course it doesn't work.
Any suggestion would highly appreciate it.
REgards,
