i use 4 sip devices (4 voip desk phone), each one configured with a different port.
I check if they work using the “extension status” tab on vitalpbx gui.
It often happens that some extension use different port from the one i set (for example in the device for the extension 1 i set port 5100 but i see that now the extension is using port 1100).
It’s due to the stun server or there are other settings to check?
I mean is strange because i set fixed port on my desk phones, and sometimes when i find the port changed, i see the error that the extension is unreachable.
Do you know if there is a solution to avoid this problem ?
