When you designate stations 144 thru 149- the only stations that CAN be voicemail ports, the system commandeers any DTMF receivers you have installed in the system for those ports. DTMF receiver cards came in bunches of 2 or 8 receivers on a card. If you only have a RECV-2 card, you'll need to replace it with a RECV-8 card, and add a 2 port daughterboard- for a maximum of 10 receivers if you have any other analog phones connected to the switch.

You must also program the system for the correct number of installed receivers.


Sometimes the thoughts in my head get so bored, they go for a stroll through my mouth. This is rarely a good thing.
