306 Called Party Control on Internal Calls
This feature is designed for stand alone application only and is not
supported across a network. On a set to set call, the calling and the called
party must belong to the same customer on the same system.
Called Party Control on Internal Calls (CPCI) is not supported on ISDN
BRI sets.
If an attendant console is the calling party and involved in a call with a set,
the CPCI feature functionality is not provided to the call.
The CPCI feature is not supported with features such as Attendant Recall,
Override, Call Park and Privacy Release.
If the system initializes during an established call, the call remains
established. Following initialization, the calling party can successfully
release from a connected call prior to the called party releasing.
For this feature, the called party must have a Malicious Call Trace Allowed
(MCTA) Class of Service configured in the Customer Data Block (LD 15).
The existing limitations of Malicious Call Trace apply to this feature. When
MCT is requested, the information is printed in the call trace record.
If the called party does not release the connection, then the calling party
remains established until the called party releases.
Feature interactions
Automatic Hold
If Called Party Control on Internal Calls is active, an established call is put
on hold regardless of the Automatic Hold Class of Service assigned to the
set when a second call is originated or answered.
Call Hold, Deluxe
The calling party and called party can put either party on hold. However,
the calling party cannot release the call while the called party is on hold.
The called party is permitted to release the call.
Held Call Clearing
With Called Party Control on Internal Call enabled, a call on hold is not
cleared when the calling party releases. This occurs whether or not the
Held Call Clearing feature has been activated.
Feature packaging
Called Party Control on Internal Calls requires the new package Called
Party Control on Internal Calls (CPCI) package 310 and also requires
Malicious Call Trace (MCT) package 107.
