› VitalPBX Community Support › General Discussion › Random port change in sip devices
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?
Thanks in advance
Phone devices usually use random ports by default for registering
Thanks for your reply.
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 ?
