MULTIPLE CALL HANDLING
(USING CALL KEYS FOR MANAGING MULTIPLE CALLS)
The Multiple Call Handling utility known as Call Key (Feature Code 66) provides a method for tracking the status for a
“pool” of CO lines. More specifically, the Call Key reflects the status of any active Trunk calls for a specific extension
(assuming there is not a Line Key programmed for that individual CO line that the Trunk call is associated with).
Furthermore, users can program multiple Call Keys on their phone to allow for tracking the status and management of
additional, simultaneous Trunk calls.
A Feature key (i.e., Call Key) can be programmed on any designated Vertical Comdial phone for use in handling
multiple calls (see
“Assigning Feature Keys” on page 442). The Call Key can be programmed on any feature key of an
extension. Once invoked, the Call Key becomes associated with that Trunk call and the Call Key lamp indicator reflects
the status of that Trunk call for the duration of that call at the extension.
NOTE
• The maximum number of Call Keys that can be programmed is equal to the
number of feature keys available on the phone being used.
• Only programmed Call Keys work. The Feature Access Code itself is not valid.
• The Call Key will work for any CO line (i.e., loop start as well as digital - T1 or T1/
PRI).
However, if you have a Line Key programmed for a particular line then the
Line Key will be used for that particular line.
In other words, Call Keys are only
associated with CO lines that do not have a Line Key programmed for them.
• The Call Key will provide status for Trunk calls whether the Trunk call is incoming
or outgoing. However, users cannot press an available Call Key to access a CO
line to initiate an outbound call.
