ABSTRACT:
Method and apparatus are disclosed for dedicating one or more second lines interconnecting a public/private communication system (PCS), such as a Private Branch Exchange (PBX), and a Voice Mail System (VMS) for only providing message notification to communication devices of recipients of voicemail messages via the PCS. A plurality of analog first lines in a hunt group between the PCS and the VMS permit voice communications between callers and the VMS via the PCS. The VMS includes an applications processor which is integrated (coupled) to the PCS. The applications processor determines if a second line to be used only for message notification is part of the plurality of analog first lines in the hunt group. If the second line is part of the plurality of analog first lines, the applications processor accesses the PCS over the second line, and causes the second line to be made inaccessible to the public/private communication system for transmitting incoming calls to the Voice Mail System. When a second line is not part of the plurality of analog first lines, the applications processor accesses the PCS, and causes all incoming calls that are directed to the VMS over this second line to be forwarded to the plurality of analog first lines.
