Call Prompting Digit Entry

For existing systems that are adding a Call Prompting application, the AT&T Account Team recommends the appropriate number of TTRs based on two factors, as follows:

■Account team input to the DOSS/ATTOMS configuration

■Application review by the AT&T Design Center

Outside callers must have a touch-tone phone to enter the digits requested via the collect digits command. For callers using rotary dialing, the Call Prompting timeout takes effect, the collect digits command times out, and vector processing continues at the next step. As a precaution, the customer should always provide a default treatment (for example, route-toattendant command, queue-to main split command) in the vector script unless the script is created exclusively for users of touch-tone telephones.

NOTE:

With G3V4 and later releases, the Call Prompting inter-digit timeout can be administered for any number of seconds from 4 to 10. This value is administered on the Feature-Related System Parameters form. See DEFINITY Communications System Generic 3 Version 4 Implementation, 555-230-655 or DEFINITY Communications System Generic 3 V2/V3 Implementation, 555-230-653, for instructions.

Provisions for users of rotary phones are illustrated in the vector scripts in this chapter.

The touch-tone digits entered by a Call Prompting user are collected via the collect digits command. This command allows the system to collect up to 24 digits from a touch-tone phone. Sixteen of these digits may be collected immediately, while any remaining digits are stored as dial-ahead digits (explained later in this chapter).

Call Prompting allows some flexibility in entering digits. Specifically, the caller can do the following:

■Remove incorrect digits strings

■Enter variable-length digit strings

■Enter dial-ahead digits

The following sections explain these processes.
