2.13 Low-level Call Control Functions
The following functions provide
low-level
access to the line interface. This access is typically only needed when using the
NOCC
(no call control) protocol. These functions are used when the application is directly controlling the line interface or a CAS protocol is not needed. Care should be taken when using these functions (especially if you are running a trunk control program).
The following AG Access functions provide low-level call control:
To...
Use...
Assert an out-of-band signaling pattern

adiStopSignalDetector
Query the current inbound out-of-band signaling bits
adiQuerySignalState
Start DTMF/MF/pulse dialing of digits
