    hello. I have a 3cx 9 sp5 system I just installed, and am getting no audio from outside of my firewall. I have a sonicwall TZ200, and the phone is a Cisco SPA504G. Using nexvortex as my sip provider

    Ports opened from the outside world: I know there are some that don't need to be open, but this really feels like a firewall issue.
    9000-9049 TCP
    9000-9049 UDP
    5481 TCP
    40000-40500 UDP
    7000-7499 UDP
    5060 TCP
    5060 UDP

    log snippit from the 3cx log file showing a call connected but I'm getting no audio.

    Sonicwalls are notorious for causing 1 way audio issues even when "Properly" configured.
    We've got a lot of forum users who've had Sonicwalls and fixed their issues, i'm sure one of them will be able to help you, Locutus of Borg soon enough. :mrgreen:
