3CX APP provisioning

[LuisR]

Hi Team,

We have 3CX on-premise.
I've been checking the ports on our firewall, making sure they work properly, but I seem to have a problem with port 5001.

Connection to that port works in the internal network, but I noticed that provisioning of the 3CX app using a mobile phone network or another external network does not work as external access is blocked on the firewall.
I have the same issue using Iphone or android device.

If a user attempts to scan the QR code, it does not work, or if we set up the app onsite and they go home, the app does not work either.

My question is Should this port be open for provisioning and continue use of the 3CX app using the external network? If yes, is there a way to change the port to another port?

if you need remote extension outside your local network, need to publish 3CX via IP Public NAT/Port Mapping on your router/firewall

for scan qr code, try to access using fqdn & https

i recomended you to setup split dns on your dns server

3CX has a built in firewall test…

Port 443 is the default now. 5001 implies an older install? AFAIK the supported way to change web server ports is to reinstall.

and yes, you need this port to use the app from external.

You said it.
