10.1 UNDERSTANDING THE DTMFINT TABLE

The DTMFXNT Table interprets an incoming D’ThIF &I record by identifying the type of call, matching it with a suitable call action by the Toshiba VP System, and collecting the Called and cal.lingPartyID.

Since each individual PBX manufacturer sends proprietary DTMF codes to identi$call types, and further, will send the various items of information in the order they choose, the DTMFINT Table is very flexible to accommodate the great variety of call record formats encountered.

The Toshiba VP System configures a default DTMFINT Table for a specific PBX model when System Parameter 3 - PBX TYPE is modified. Selecting and configuring the default DTMFINT Table is independent of selecting default PBX system parameters. Therefore, the detailed configuration information contained in this section is usually used to modify a default table.

The key to understanding the DTMFfNT Table is to recognize that the order of elements in a call record format specified by the PBX manufacturer is the pattern that the DTMFINT Table must reproduce. The string of DTMF digits sent by the PBX to the Toshiba VP System contains some or all of the following items:

lCall typecode

=Calling party ID

0 Miscellaneous field separators

Configuring the DTMFINT Table requires identifying all the possible call record formats (20 maximum) that will be sent as DTMF digits and making entries in the DTMFINT Table to match them. The types of calls that a particular PBX can support depends on the PBX’s own capabilities.

The first set of DTMF digits in a call record is the call type code which is a fiied DTMF digit string and must be unique. For each unique call type, a Toshiba VP System call action is assigned that determines which prompt the system plays and action it takes. The system interprets the remaining DTMF digits in a call record according to the specific call record type.

The following is an example of a DTMFINT Table.
