Telephony Application Programming Interfaces

Overview of the Telephony Application Programming Interfaces technology.

To develop Telephony Application Programming Interfaces, you need these headers:

For programming guidance for this technology, see:

Class

 
CMSPAddress

The CMSPAddress class implements the MSP address object and supports the ITMSPAddress interface. This class is defined in MSPaddr.h. The following documents the class.
