If you are having trouble getting/making calls using the TeleMessage Enterprise Number app in some locations, it might be related to the fact that you are on WiFi and the WiFI router at these locations is blocking some of the ports we’re using to communicate between our server and apps when delivering calls.

As a temporary workaround, you can try disabling WiFi on your phone, to route the traffic via the phone data plan.

Alternatively, request IT personnel who manage the WiFi hotspot to open the following ports in the firewall:

Minimum required ports:

From and To DNS : http://kamprod.telemessage.com  Port: TCP/443
From and To DNS : http://tlxturn.telemessage.com  UDP/80
From and To DNS : http://tlxturn.telemessage.com  TCP /443

Other required ports:

From and To DNS : http://archive.telemessage.com  TCP /443

Recommended additional ports:
