    From time to time I'm seeing the following error messages in the 3CX Server Event Log:

    Call to Primus SIP Trunk has failed. sip:xxxxxxxxxx@bvoice.primus.ca:5060 replied: 504 Overloaded; from IP:

    This results in the system being unregistered until 3CX tries again five minutes later.

    Anyone have any idea where I should be looking for the problem? Is it something on the provider side, or a problem with my 3CX setup?

    Thanks in advance,

    Pretty sure that is a provider side error. I think errors in the 500-5xx range are server error responses

    504 - Server Timed Out

    It is message from the Primus server that it did not receive a response from the gateway (server) it was placing your call on, so a fault on their side.

    This is a full of list of codes I have

    100 Trying: Extended search being performed may take a significant time so a forking proxy must send a 100 Trying response
    180 Ringing: Destination user agent received INVITE, and is alerting user of call.
    181 Call is Being Forwarded: Servers can optionally send this response to indicate a call is being forwarded.
    182 Queued: Indicates that the destination was temporarily unavailable, so the server has queued the call until the destination is available. A server may send multiple 182 responses to update progress of the queue.
    183 Session in Progress: This response may be used to send extra information for a call which is still being set up.
    2xx—Successful Responses: 200 OK
