Collect DTMF Digits - Feature

The capability to collect Dual-Tone MultiFrequency (DTMF) digits from the customer is available. Upon receiving a request to collect digits, the TSP500 optionally plays a voice message and collects the requested number of digits. The TSP500 responds with a completion message when the digits have been collected.

To support the collecting of digits, a new Protocol C Message

M_COLL_DIGIT has been defined. The M_COLL_DIGIT message requires the number of digits to collect, and optionally the time to wait (in seconds) before digit collection expires and the terminating key to end digit collection. If a timeout value is not supplied, the timeout defaults to ten seconds. If a ter- minating key is not supplied, the key defaults to the pound key (#). Addition- ally, the M_COLL_DIGIT message permits the sending of a voice message to be played while collecting digits. The voice message in the “key” field descriptor and the “flag” field descriptor function the same as described in “Text-To-Speech (TTS) Messages” section except that the message can be interrupted by pressing a telephone digit key.

When the request has been satisfied or the timer has expired, a route request (M_ROUTE_REQ) is sent to the Adjunct. This M_ROUTE_REQ message has been modified to send a new result code, SWR_COLL_DIGIT_DONE, indicating that digit collection completed. If digits have been collected, a new field descriptor “user data” is filled with the digits collected and sent to the Adjunct. The “user data” field descriptor is designated with the letter “u”.
