GotDigits indicates that digit(s) have been received on the call control protocol signaling path, for a a particular CallId

GotDigits provides no means of pattern matching. The GatherDigits action in the Media Control API provides more powerful operations for developers to determine if a certain pattern or other condition is met by the digits being inputted on the call.

The Call Control API makes every effort to abstract the complexities of the underlying telephony protocol; however, one should consult the Call Control Feature Matrix to understand what Call Control actions and action parameters are valid for each of the four supported protocols. One can set installation and deployment guidelines based on the Call Control actions and action parameters that an application uses; the Call Control Feature Matrix makes developing such guidelines feasible.
