port numbers

  1. SBC Tunnel ports.

    First time using a hosted PBX. It will have 3 different locations. I've got three raspberry pi's setup as SBCs. Do I need to setup any forwarded ports? They seem to work fine but I don't want to have intermittent problems down the road.
  2. Changing Port Numbers for testing

    I am wanting to test 3CX on a local install, but we currently have another IP phone system live in production, that is using some of the default recommended ports. Does anyone know of any issues that I might incur if I just add a 1 to the port numbers, instead of 5001 > 15001 for HTTPS etc...
