1161Automatic Callback
20
NOTE:
If the automatic callback originator has all line appearances occupied
when the automatic callback call comes in, the user will hear priority
ringing once, and the automatic callback lamp will blink. However, if
the user presses the automatic callback button to answer the
automatic callback call, one of the other calls will drop.
Interactions
■ Attendant Call Waiting and Call Waiting Termination
If a user activates automatic callback to or from a single-line telephone,
Call Waiting Termination is denied.
■ Attendant Intrusion
Attendant Intrusion does not work if a user has activated automatic
callback.
■ Bridged Call Appearance
Users cannot activate automatic callback from a bridged call appearance. If
a user activates automatic callback from a primary extension number, the
return-call notification rings at all bridged call appearances.
■ Busy Verification
If a telephone has activated automatic callback, you cannot perform Busy
Verification of that telephone.
■ Call Coverage
Automatic callback calls do not redirect to coverage.
■ Call Forwarding
If the called telephone has Call Forwarding activated, the calling party
cannot activate automatic callback. However, if automatic callback was
activated before the called telephone user activated Call Forwarding, the
system redirects the callback call attempt toward the forwarded-to party.
■ Call Pickup
A group member cannot answer a callback call for another group member.
■ Class of Restriction
Telephones with origination restriction cannot activate automatic callback.
■ Conference and Transfer
A single-line telephone user cannot activate conference or transfer if
automatic callback is active.
