The last port on the Merlin Mail unit would be the the relevant extension number for that port on the 012 or 016 card. Go to maintenance, port, station, enter the port number of the last Voice Mail port (count each station (non-line)port starting with 1 from the first module to next to the processor to whereever you have your mail unit plugged in). If you miss count but are close, you can use "next" to move up a port. Choose "status" and under "slot/port" you will see a 4-digit number - which uses the first two digits for the module "slot" and the next two for the "port" of that slot. Make sure you are on the right slot that the mail unit is plugged in to. Once you have the port number you can check the status of the slot or reset it.
