    I have installed 3CX and utilizing the iPhone app. I am not having any making phone calls as it continuously says forbidden. Internal extension or external dialing. Doesn't matter. All forbidden. Here is a copy from the server logs.

    14:48:44.207 [CM503013]: Call(10): Incoming call rejected, caller is unknown; msg=SipReq: INVITE 103@24.120.119.213:5060 tid=PjSm6OCBK1Skw-6JeB.xJYbA6gL9iaQCh1 cseq=INVITE contact=100@24.234.42.140:5065 / 4345 from(wire)

    Is the phone trying to make a call from OUTSIDE the network. It seems like that is the case as I see different IP addresses.
    In the extension setup for 103 - do you allow calls from outside the LAN ?

    correct,

    the local SIP domin in your 3cx phone system is not set to "24.120.119.213"
    Internaly we can read form the NIC the IP and if this matches the Invite we grant the call.
    But your Public IP we dont see on the local NIC, so once you come from external we will block you.
