Has anyone had any luck with getting 3CX working behind UT7.1 with a SIP account from callcentric.com?

I am willing to reset my current UT box back to defaults, and start from there.

I have a static public IP assigned to the external interface.

My internal addressing is 192.168.76.0 .

My 3CX box has 192.168.76.17 .

Would anyone be willing to give me a step by step of changes to make in UT / 3CX.

I currently have my UT box unplugged, and have replaced it with a Linksys unit. I have port forwarding setup for…

TCP/UDP 5060 to 192.168.76.17 UDP 9000-9049 to 192.168.76.17

… and everything works great.

I also have additional external IPs available if that helps.
