Toshiba VP 300, Installation Instructions Manual

Page: 416 / 614

In the case of a direct call, the VP 300 answers with the Company Greeting corresponding to the trunk
group the call came in on, if trunk group ID is provided in the call record
Calls placed to extensions from the Company Greeting are typically released to ringing. If DID
service is available, calls may also be placed directly to extensions. In either case, on a busy or no
answer, the call is automatically forwarded back to the VP 300 pilot number (e.g., 2500), along with a
call record. Depending on the information in the call record (called party ID, called party status,
calling party ID), the VP 300 can customize how the call is answered, letting the caller know that the
person was busy or didn't answer, as well as provide identification of an internal caller in the
message.

RS-232C Data Link Integrations
RS-232C data link integrations transmit encoded call records with information about the port on which
the call is received. The separate data and call signals are associated and processed by the VP 300. CO
Centrex is one type of RS-232C data link integration. Several PBX manufacturers also use a call
record similar to Centrex SMDI, or some proprietary call record scheme. See Chapter 9, Centrex
SMDI/SMSI Adaptive Integration, for detailed information.
Figure 8-2 illustrates the interaction between the VP 300 and the PBX in an RS-232C Data Link
Integration environment. An explanation of Figure 8-2 follows the diagram.
1. In an RS-232C Data Link Integration, the VP 300 can receive direct calls to the pilot number.
2. The VP 300 can also receive forwarded calls from busy or unanswered extensions.
