Inter-PBX Attendant Service
Inter-PBX Attendant Service (IAS) allows attendants for multiple branches to be
concentrated at a main location. Incoming trunk calls to the branch, as well as
attendant-seeking voice-terminal calls, route over tie trunks to the main location.
How to administer
Inter-PBX Attendant
Service
Detailed description Inter-PBX Attendant Service calls are incoming tie-trunk calls from a branch location
to the main-location attendant group. If no attendant in the group is immediately
available, the calls are queued. When an attendant becomes available, the call routes
to that attendant. Extended calls are treated as incoming calls to the main location.
DEFINITY ECS can be a branch or main location. Users at each branch can access
other branch locations through the main location. A branch can have local attendants.
Users access these local attendants normally.
Interactions • Attendant Control of Trunk-Group Access
If a call at a branch attempts to access a controlled trunk group, the call routes to a
branch attendant, if there is one. If there is no branch attendant, the call routes to
the attendant group at the main location.
• Attendant Display and DCS Attendant Display
In a DCS environment, an incoming call from a branch displays at the attendant
console at the main location as a local call.
In a non-DCS environment, an incoming call displays at the attendant console at
the main location as an incoming tie-trunk call.
• Attendant Recall
If an attendant at the main location holds a call, the calling parties at the branch
cannot recall the attendant.
• Call Coverage
A call redirected to a coverage path with the attendant group as a coverage point
skips that coverage point. It goes to the next coverage point at the branch, if
administered, or continues to ring at the previous coverage point. If the attendant
group 0 is the only coverage point, it continues to ring at the principal’s extension.
