Features
Attendant Call Queuing
n Description
Attendant extensions can have up to 32 internal incoming calls queued before additional callers hear
busy tone. This helps minimize call congestion in systems that use the attendant as the overflow
destination for unanswered calls. For example, you can program Direct Inward Lines and Voice Mail
calls to route to the attendant when their primary destination is busy. With Attendant Call Queuing,
these unanswered calls would normally "stack up" for the attendant until they can be processed.
Attendant Call Queuing is a permanent, non-programmable system feature for each telephone assigned in
Program 20-17-01.
Attendant call queuing is automatic for incoming exchange line calls to a Ring Group (Program 22-04-01
to place phones into ring groups).
The 32 call queue total include Intercom, DISA, DID, DDI, DIL and transferred calls.
