    Starting about a week ago my 3CX system loses registration with my VoIP Provider. I checked with them and everything is fine on their side.

    Things i've currently tried:
    backing up and restoring 3CX (resolved some limit issues ive had in the past. so gave it a shot) No luck
    uninstalling and reinstalling 3CX (still no avail)

    Current changes ive made.
    Ive added the public IP into the Network tab. Dont think this would cause the problem.
    Setup an external extension phone.

    Any ideas why this error would occur?

    Here is what event viewer is telling me.

    Description: [CM104001]: Registration at 'lax.teliax.com' failed Host 'sip:(username)@voip-co4.teliax.com:5060' is not available!

    Hi
    I expect to see Host only 'voip-co4.teliax.com' here :roll: Usually, to check if a host is reachable, try a ping to it.
    Hope it helps

    Hi,

    As Vali said the PBX is screaming that they cannot reach the voip provider at that specific address, ask if they have another one a stronger one maybe that you can change to. If they say its not the issue try ping it as soon as you cannot register with it and see if its available at the time.

    Thank you Mark and Vali,

    I had our provider switch it to Los Angeles instead of colorado yesterday. Checking the event viewer it was a lot more solid. Instead of failing 12-16 times it only went out 6 times. I will try pinging next time it goes down.

    latest log

    Code:

    Be careful, 503 error may also means the port is not good, not only the host. In such case, better than ping - which check only for hostname - a better test is a telnet to the specified host and port, in our case to lax.teliax.com 5060.
