Callback Requests are protected by system memory battery backup.
When a Callback Request is set, the caller receives a set tone.
A caller does not receive a set tone when attempting to leave a
Callback Request at a station with three Callback Requests set.
Callback Requests that are set in the system can be canceled
(system-wide) only at Attendant Positions.
Individual Callback Requests are canceled when:
1. Callback recipient places internal call to Callback originator.
2. Callback originator places internal call to Callback recipient.
3. Callback recipient enters Feature, 99, Feature.
A Callback Request can be set to a Single Line Telephone (SLT), but
there is no indication at the SLT. The SLT user can still go Off-hook
and dial # to complete the callback.
