With Dial-ahead digits, callers can skip announcements. Only subsequent collect digits commands can use the digits. Other vector commands that operate on digits, for example, route-to digits and goto...if digits, do not use the digits until Communication Manager collects the digits.
Communication Manager does not forward the digits with interflowed calls and does not display the digits to an agent who presses callr-info until Communication Manager completes the collect digits command operation.
Collection of dial-ahead digits continues until one of the following occurs:
Vector processing stops or is terminated.
The sum of the digits collected for the current collect digits command plus the dial-ahead digits exceeds the storage limit of 24. Communication Manager discards additional digits until subsequent collect digits commands create more storage.
Note:
Asterisk (*) and pound sign (#) digits are part of the 24 digit limit, as do any dial-ahead digits that callers enter after the asterisk (*) or pound sign (#) digit.
The TTR required by the caller to collect digits is disconnected, which can happen when one of the following conditions is true:
A successful or unsuccessful route-to number step is encountered during vector processing, except where the number routed to is a VDN extension.
A successful or unsuccessful route-to digits step is encountered during vector processing, except where the number routed to is a VDN extension.
A successful or unsuccessful adjunct routing link step is encountered during vector processing.
A successful or unsuccessful converse-on step is encountered during vector processing.
A Call Prompting time out occurs, during which time the caller does not dial additional digits, asterisks (*) sign, or pound sign (#).
Vector processing stops or is terminated.
A successful or unsuccessful collect ced step or cdpd step is encountered.
When the TTR is disconnected due to a route-to number, route-to digits, converse-on, adjunct routing link , or collect ced/cdpd step, Communication Manager discards all dial-ahead digits. Therefore, following a failed route-to, converse, or adjunct routing link step, a subsequent collect digits step always requires callers to enter digits.
