Solved After IP change Softphone is not working out of LAN

[gvsoft]

Hello to all,

We recently changed our IP of the 3cx Local machine and are having trouble now in getting the softphones (client) out of the LAN to register.
What can we do about this. I have tryed to resend the welcome email but still having timeout problems.

Hi @gvsoft

if the LAN IP changed, it means that any port forwards you had, are now broken.

The clients will reach those ports from outside, but the firewall is not sending them to your pbx machine

Thank you for the answer! I did change everything in our firewall and everything is playing fine! Thank you again!

Glad to hear it was resolved

For the ports 10600 - 10998 are we to use UDP / TCP or Both for the port forwarding?
