Good morning, I seem to have a chronic problem with my VoIP lines unregistering and not re-registering once a week. It appears that every Saturday around 11am all my VoIP lines become unregistered. They then will not register for several hours. Then all of a sudden they all register. Wireshark and the logs show 3CX attempting to register but the VoIP provider states that they aren't recieving the registration requests. I am able to register the lines just fine from the same subnet using X-Lite during this same period of time. Anyone have any ideas as to what might be going on? Network traffic durring this time is minimal and I have turned QOS on and off to see if there is somthing there causing problems (no effect). I have also restarted the 3CX server. Changed the proxy settings, DNS is working properly, etc.
