    I am having trouble figuring out what I need to do. On the PBX (3cx) i have set the stun server to stun.3cx.com and on the hardware phone I have set the stun server to stun.3cx.com for the sip server I entered the public IP of my router (which is static) and the sip user id and authentication id I set to the extension that I have set up for it. Now when I change the SIP Server IP on the Phone to the local IP form my PBX it works, but when I try to use STUN so that I can have a phone/extension out of the office and I set the SIP server IP to the public IP it will not work. Any Ideas? I have 3 pictures of the setup screens:

    how it works

    Once I forwarde the ports 5060 - 5061 udp to my pbx and had stun setup on the phone (sip.3cx.com:3478) and stun on the pbx set to sip.3cx.com then everything worked on the remote phone side of things.

    Make sure you have the STUN port (3478), as well as the line ports (7000-7499 for internal calls, and 9000-9499 for external calls) open and forwarded to the 3CX machine.
