Hi, If this has been posted already somewhere then I am sorry, but I have been searching high and low but cant find the answer.
I have two providers, SIPGate and Gossiptel. SIPGate is working perfectly but I still have trouble with Gossiptel.
Finally I found that if I set ‘externip’ in sip.conf to a numerical IP address, gossiptel works fine, but as I have a dynamic IP address, I use a DynDNS entry.
When I use a DynDNS entry, rather than a numerical IP, I only get one way transmission, outbound.
Does anyone know of a fix for this please?
