Appendix A. CPC-EX 2.3 Feature Update Section 530-ISDN Ref.
Page A-8 DBS Manual - Revised April 2000 DBS-2.3-400
Operation
When the UNA Reversion Timer is set to 0, a call that reverts to the attendant
and is not answered, continues to ring at the attendant. It does not revert to
UNA. When the UNA Reversion Timer is set to a value other than 0, a call
that reverts to the attendant and is not answered within the specified time
reverts to UNA.
To answer a UNA call:
1. Go off-hook.
2. Dial 78.
or
1. Directly pick up the trunk by pressing the dedicated trunk key.
Notes
• When a call reverts to UNA, the UNA will continue to ring until the call is
answered (by dialing 78 or by direct trunk access) or the caller hangs up.
• If multiple callers ring the UNA, the UNA calls are picked up on a first-in/
first-out method.
• The Call Reversion Timer must be set to “revert calls to the attendant”
position for unanswered calls to then be reverted to UNA.
*Forwarding to UNA for CO Held Call
Description
An extension can forward certain calls to UNA. If an inside extension (such
as an automated attendant) receives a CO call, it places the CO call on hold
and dials the forwarding extension. Then, the call will forward to UNA.
Internal calls, direct calls to the forwarding extension, or T1 network calls
ring the extension. They do not forward to UNA.
This feature is particularly useful in a situation when calls come into an
automated attendant and then, on caller selection, may transfer to an
extension such as the attendant. When the extension user goes on break etc.,
the calls can be forwarded to UNA to ensure that the call is handled.
