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.

Automatic Route Selection (ARS)

If a user with a multiappearance telephone that has an Automatic Callback button makes an ARS call, and all trunks are busy, the system activates Ringback Queuing automatically.

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 user has activated Automatic Callback on a telephone, you cannot perform Busy Verification of that telephone.

Call Coverage

If the calling station has Call Coverage active, the callback terminates at the called station and does not follow the coverage path.

Call Forwarding

If the calling party has activated Call Forwarding on a telephone, the calling party is able to activate Automatic Callback. If the called party activates Call Forwarding on a telephone before the caller trying to use Automatic Callback, the calling party is unable to activate Automatic Callback. Also, if Automatic Callback was activated before the called telephone user activated Call Forwarding, the system redirects the callback call attempt toward the callback party, not to the forwarded-to party.

• If the calling station has Call Forwarding active, the callback is forwarded only if the forwarded station is local to the calling station. You cannot activate Automatic Callback if the forwarded station is remote to the calling station.

• If a forwarded station that has active automatic callback has any activity going on, callback is not generated till one of the following conditions is met:

  • the forwarded station goes on hook

  • the forwarding is removed and the user goes on and off hook

• Automatic callback cannot be activated if the called party is forwarded to a station that is forwarded to another station.

Call Pickup

A pickup group member cannot answer a ringout call. For information on ringout call and callback call see Detailed description of Automatic Callback.

Telephones with origination restriction cannot activate Automatic Callback.

Conference and Transfer

A user of a single-line telephone can activate conference or transfer if Automatic Callback is activated.

Distributed Communication System (DCS)

Automatic Callback operates over a DCS network in the same way that Automatic Callback operates on a local server.

Expert Agent Selection (EAS)

Users cannot activate Automatic Callback to the login ID of an EAS agent. Users can activate Automatic Callback to the telephone where the agent is logged in.

Hold

A user of a single-line telephone cannot receive Automatic Callback calls if the user has placed a call on hold.

Hot Line Service

Internal Automatic Answer (IAA)

IAA does not automatically answer Automatic Callback calls.

Manual Originating Line Service

Telephones with Manual Originating Line Service cannot activate Automatic Callback.

Personal Station Access

You cannot activate automatic callback to a disassociated PSA extension unless that extension is bridged to another physical station. If callback was activated before the disassociation, the callback remains in queue till the activation timer expires or the callback is explicitly canceled.

You cannot activate automatic callback from a disassociated PSA extension.

Public Network Trunks

Automatic Callback works on outgoing public network trunks in some countries. The call must be dialed using AAR, ARS, or UDP. Automatic Callback cannot be activated on a public network trunk call if the call was dialed using a Trunk Access Code (TAC).

QSIG

Automatic Callback operates over a QSIG network in the same way as on a local server. The call must be dialed using AAR, ARS, or UDP. Automatic Callback cannot be activated on a QSIG call if the call was dialed using a Trunk Access Code (TAC).

Remote Access

Callback calls cannot be made to Remote Access users, because the system does not know the calling number.

Ringback Queuing

Users can press an Automatic Callback button to activate Ringback Queuing.

Send All Calls

You cannot activate automatic callback on a station that uses the Send All Calls redirection option.

Telephone Display

When the system generates an Automatic Callback call, the display of the originating telephone displays Automatic Callback, or the equivalent translated phrase for Administrable Language Displays.
