User actions
The party receiving a Call Offer has three choices:
• Ignore it. After a programmed time interval, the Offer request is removed.
• Reject it. If the user activates Do Not Disturb on Busy (DND) when the Call Offer request is
made, the request is removed from the telephone. The calling party is informed of the
rejection.
A call cannot be offered to a telephone with DND active. The line indicator for external
incoming calls still flashes.
• Accept it. The Offer is accepted by releasing the active call.
Note: Forward on Busy takes priority over DND on Busy. Call Offer cannot be accepted by
putting an active call on hold.
Route optimization
Route Optimization is a DPNSS 1 feature for Business Communications Manager that allows calls
to follow the optimum route between two end PBXs. This allows efficient use of network
resources.
Route Optimization is initiated by the system and is transparent to the user. However, the user may
see a call switch from an appearance on the telephone to another appearance key or from an
intercom button to the appearance key or vice versa. This occurs when Business Communications
Manager receives a Route Optimization request and initiates a new call to follow the optimal
route.
If a telephone is active on a private line call, the Route Optimization call being established may go
on a public line. This will cause a loss of privacy on that line.
Data calls are rejected by Route Optimization in order to ensure the data transmission is not
affected.
Certain situations result in Route Optimization not taking place. For example, calls that are using
Hold, Parking or Camp features do not undergo Route Optimization, and if a Route Optimization
call undergoes Diversion, the Route Optimization is dropped.
Setting Route Optimization
There is no system programming required for the feature when Business Communications
Manager is working as a terminating PBX system. However, Business Communications Manager
must have a private access code programmed that maps to a valid destination code or line pool
code on DPNSS lines. Further, Allow redirect must be set to
Y . For more information, see
“Defining device capabilities” on page 417 .
