Programming Operations Guide
Call offer
Call Offer over DPNSS 1 allows a calling party to indicate to the wanted party that there is an
incoming call available, even though there is no answer button available to present the call on the
telephone. The intended recipient can ignore, accept, or decline the offered call. Call Offer is
useful in increasing the call-coverage capability of a Business Communications Manager system,
and helps to lift the network processing load. It is a receive-only capability on Business
Communications Manager: incoming calls would be initiated at another PBX system on the
DPNSS 1 network.
An example of Call Offer in use is an operator or attendant who has a number of calls coming in at
once. The operator can call offer one call and move to the next without waiting for the first call to
be answered.
Call Offer Displays
When a Call Offer is made by the originating exchange, the target telephone displays a message,
and a tone is heard. When an offered call arrives on telephones with line display, the user sees
XX...X wtng
if the calling party ID is available and CLID is enabled. If CLID is not available
or CLID is disabled, Line XXX waiting appears (the line name associated with the call). If
there are more than 11 digits in the incoming number, only the last 10 will display.
If Call Queuing is programmed for the system, the display shows
Release Line XXX
.
This is the line name of the highest-priority queued call if it is an offered call.
