The evolution of voice mail from Avaya for the Partner telephone systems includes:
Partner Mail - an external PC with voice cards that connects to station ports on the phone system
Partner Mail VS - a module that slides into the carrier like the other cards - 5 different releases offering various features, number of ports, and number of mailboxes.
Partner Voice Messaging PC Card - a PCMCIA card that goes into the card slot of the ACS Processor - a single auto attendant, 4 or 16 mailboxes, 2 ports
Partner Messaging - a module that slides into the carrier. Offers 2 to 6 ports, 200 mailboxes, 4 auto attendants, Day and Night service, internal Business Schedule that can be used to change the mode automatically, outcalling, dial by name directory. The currently produced version is Release 7.
The Partner Mail, and the Partner Mail VS are manufacture discontinued, and have been for some years. Anyone offering such a unit will have to warranty it themselves.
2. VS Mail DOES offer a Day and a Night message.
3. Yes, I really mean go down to the Office Supply Store, and buy an answering machine. Plug it into an extension port on the phone system, and it will answer calls directed to it. By programming the Night Service button, the Night Service Group, and the VMS Hunt Schedule, the Night Service button can toggle the Auto Attendant OFF and the Answering Machine ON.
4. An ASA/DXD card goes into the ACS processor's 2nd PCMCIA card slot. ASA is a feature that answers a ringing call, plays a short message, and puts the caller on hold until the call can be picked up. DXD acts as a small auto attendat, which answers a ringing call, plays a short message, and waits for the caller to dial an extension number. Both functions come in the same PC card. Will it solve your problem? It's just one approach to designing a solution.
