    Ran out of DNS Entries Send 503 in the IPCM log files


    This is the result of a network issue and a send 503 message will show in the logs. 503 error message for SIP means service unavailable. 

    The message about running out of DNS entries means that the system was trying to contact another machine and was not getting responses and all available naming conventions for the machine had been tried so it 'ran out' of ways to contact the machine in question.
