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 set. The intended recipient can ignore, accept, or decline

the offered call. Call Offer is useful in increasing the call-coverage capability of an

Enterprise Edge system, and helps to lift the network processing load. It is a

receive-only capability on Enterprise Edge: incoming calls would be initiated at

another PBX 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 extend one call and move to the next

without waiting for the first call to be answered.

Displays

When a Call Offer is made by the originating exchange, the target set displays a

message, and a tone is heard. When an offered call arrives on sets with line display,

the user will see XX...X wtng if the calling party ID is available and CLID is

enabled, otherwise, Line XXX waiting is shown (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 will show

Release Line XXX.

This is the line name of the highest-priority queued call if it is an offered call.

Restrictions by set type

Call Offer is indicated differently on different types of sets:

• M7000—The associated LED or LCD will flash, and a tone is heard.

• ATA—Call Offer is supported as a Camp On feature and a tone is heard.

• ISDN—Is not supported.

• Portables—Is not supported.

• DNA—Is not supported.

Note the following general conditions and restrictions:

• DND on busy must be programmed as N (see Terminals & Sets, Capabilities)

for a set to accept Call Offer.

• If CF on busy is programmed for the set, Call Offer will not be accepted.

• The target line for the set must be set to: If busy: busytone,which is the default

(see Trunk/line data on page 111).

• Call Offer will not work if sent over Manual answer lines. Again, it is

recommended that for the majority of purposes, lines be left at the default:

Auto.
