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, you  can program multiple Call Keys on your 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*.  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. 
 
 
 
 
 
*Check with your System Administrator to find out if your phone 
 is programmed for handling multiple calls as described above. 
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, you cannot press an available Call Key 
to access a CO line.
