Okay, I have been working on getting 3cx working for the past week and am still having one major issue. I am not able to get remote softphones to connect and I am receiving an error on the firewall test that seems odd. I'll start by giving you the basic configs. 3cx phone system installed on PC behind Belkin router with static ip Static WAN ip is 76.252.xx.xxx 3cx phone system ip = 192.168.2.2 All ports needed are forwarded to 192.168.2.2 including tunnel 5090 I have also tried the firewall test with the PC set as DMZ on the router Here is the main error I keep getting on the router test. Error 13: This Machine is on a public IP - agentAddr = 87.230.29.xxx:4200 This is really throwing me off because I have no clue where this ip is coming from or what it is. I get this firewall error everytime regardless, yet when first installed I thought I had gotten a "Router Test PASSES" but I may be wrong. I have been able to get the softphones to connect once or twice, not sure what settings I was using, but the phones would register. Although the phones would register, they could not make or recieve calls from the other extensions, and thier status would never change on the "Line Status" page. I am completely stuck at this point. I have also tried the tunneling option, and think I had the settings correct but still had no luck. I may be a little confused on what exactly the ip address of the "Proxy Server" is supposed to be. Is this just supposed to the local machine running the PBX System. PLEASE HELP. I'm losin it. I am more then happy to provide server logs, or even give an address for anyone who wishes to log into the web based admin, or my router, heck, I'll give you a VNC address and let you remote right in if it will help. Anything you need. Thanks alot. P.S. On a positive note, I am switching from Axon to 3cx because of how much nicer the web admin and setup is, as well as its the first one to work correctly with some dtmf issues we were having. If I can get it working I think Im going to love it.
