| UNIT 4: PROGRAMMING - LESSON 3: SYSTEM PROGRAMMING BY PC Voice Mail Groups Read pages 130 through 143 in the KX-TAW848 Features Manual The KX-TAW848 supports two types of Voice Mail groups (DPT and DTMF) that are used to integrate either a Panasonic Voice Processing System (VPS) or similar product. Within this section we will concentrate on Digital Proprietary Telephone (DPT) Integration, which allows seamless communication between the Main Unit and Panasonic’s KX-TVS Voice Processing Systems (VPS). Together they provide features and capabilities unachievable when using traditional voice mail systems relying on DTMF Integration. A Voice Mail (DPT) Group is a group of Proprietary Line Card or Hybrid Line Card extension ports that utilize Digital Proprietary Telephone Integration to communicate with the VPS. The Voice Mail (DPT) group should only be used when installing a Panasonic KX-TVS Series Voice Processing System (VPS) that supports DPT integration. Up to 4 Hybrid Line Card (HLC) or Proprietary Line Card (PLC) ports (8 voice channels) can be used in a DPT group. Creating A Voice Mail (DPT) Group To create a Voice Mail (DPT) Group you must first change the Terminal Type for each port from “Normal” to “Voice Mail” using the Configuration–Extension Port Menu. Then the voice mail port numbers can be set to match the order in which the ports will be physically connected to the VPS. Keep in mind that all the ports used to make up a DPT Group must be located on the same HLC or PLC card. Click here to see how to create a Voice Mail group Once the Terminal Type has been changed, a floating extension number and group name can be assigned. The Floating Extension Number allows the voice mail ports to be set as the destination for incoming, forwarded or redirected calls. The Voice Mail Group can receive calls through the Floating Extension Number, or through one of the group's extension numbers directly. However, when calls are directed to the Floating Extension Number they will hunt for an available (idle) extension beginning with the lowest numbered port assigned to the group. This is why the Floating Extension Number should be used when forwarding and routing calls to the group. When all extension ports in the group are busy, additional calls to the group will be handled according to the "Call Waiting on VM Group" setting (enable or disable). When enabled, callers hear a ring-back tone while waiting for a voice mail port to become available. If disabled, calls will be redirected to the Intercept Routing destination for the corresponding CO line group.
