have you tried going to your 3CX network settings switching your External IP Configuration to dynamic mode?

 

[mohamed hamed]

no i just change (Enter your static public IP) to the new one

 

[JohnS_3CX]

So if your modem/router/firewall has a new IP now, you just need to go to your 3CX Dashboard under

Settings > Network > Public IP Tab > External IP Configuration and change the setting from Static -> to Dynamic.

After a while your system will automatically detect the new IP and show it, then you can switch it to Static again when you are ready.

i did it but still detecting ....

You can try restarting all your services now from the Dashboard, to force the detection to take place immediately.

Sounds like you are having network issues, I would start by checking by network setup from the beginning, including any firewall rules, static routes etc before even touching the PBX to confirm that the computer can reach the internet successfully
