Hi, i have a little problem: First i register all the lines at the voip provider...some days/weeks later all lines are not unregistered? LOG: ServRegs:checkExpiration [CM13000] Registration for sip: email@example.com. has expired. This happens with all lines. Only when i register each line manually they are registered. The settings are: Time between registration attempts: 360 (seconds)??? So 3CX Software should do it automatically. Or is there an other problem???
