CTI Client telephony functions (ActiveX)

Telephony functions

Use of the telephony functions

The TAPIMaster® interface encapsulates the TAPI interface, providing a substantial reduction in the number of interface commands. The functions listed below provide control of the telephone or similar functionality. Not all functions are possible with all switches – it depends on how much the driver supports.

To allow differentiation of calls, each call has a unique ID (not related to the telephone number) in the TAPIMaster® interface. You should store these numbers internally as they are required by many of the telephony commands. The numbers are known as Call IDs.

The telephony functions start with the prefix "T".
