I am trying out the free 1 year license for Zulu but cannot get the Mobile app and Softphone to work.
The server is hosted in a data centre and I control the firewall. Nothing is blocked for the PBX
The Softphone on Windows:
I can make and receive calls but as soon as I answer the call it drops.
The Mobile App:
Cannot make or receive calls on the app. When dialling numbers the call button is greyed out. The Account is registered.
Are their any additional ports that I need to allow although nother to and from the VM is blocked?
