    Hi chaps,

    If we don't want to connect any phones externally to our 3cx server and the 3cx server will only be making and receiving calls from a SIP trunk provider, what ports need to be opened on our firewall?

    We currently have 5060 UDP/TCP, 5090 UDP/TCP and 9000 to 9050 UDP/TCP. I suspect that some of these may be required just to support some external handsets at remote sites that we no longer have and I want to tidy up the rules a bit.

    Thanks

    Olly
