We are continually getting errors for similar to the one below. The endpoint 7496 is a valid extension and works without issue. The extension portion of the error is not a number that we use in our inbound or outbound rules. I have check every table in the asterisk DB and cannot locate these numbers anywhere. The only thing I believe it may be (though have no idea where to look) is a file was uploaded of number for a broadcast calling campaign that played a recorded message to our clients. This campaign was removed over a year ago.

Note when we delete some extensions (imported from previous server) we get a similar error
