I have an issue with one 3CX server. Randomly all the SIP trunks will de-register and the only way to register them is to restart all services. After speaking to someone he mentioned that its likely the UDP traffic for the RTP and that a drop in the internet connection is causing the issue. Can anyone suggest how I resolve this issue? The solution given to me was to host the server and then deploy an SBC. I would like a more immediate solution.
