Intercept Conditions 
 
Implementing features, see also Manager E Intercept Conditions

Definition  
Intercept forwards incoming calls to another destination. A call is intercepted if the original destination is invalid or if limitations exist.
Users can specify the following as intercept destinations:
 •   PC AC
 •   Stations
 •   Hunt group
 •   Announcement (external announcement device)
If an intercept position or AC is configured in the system, calls are routed to this intercept position during an intercept. If an intercept position has not been configured, intercepted calls are signaled at the station that has a call assignment for the intercepted trunk.
During intercepts, call management is entered using the intercept station as the basis. If the intercept position cannot be reached, the call is signaled at a night bell, if entered, or the call waits in a queue at the intercept position.
Users can activate the intercept feature under the following conditions:
 •   Intercept no answer
    If there is no answer, the call follows the entries in call management. If the end of the CM elements is reached, the system determines whether or not an intercept after timeout should occur. Calls are intercepted if they cannot be switched because there are no available stations.
 •   Intercept busy, if no additional forwarding is possible.
    If a station is busy, the system determines whether or not call waiting is possible.
    If call waiting is not possible (signaling security or intercept criterion), the call follows the entries in call management. If the call cannot be signaled at any station, the system determines whether the call should be intercepted or released.
    In general, intercept busy only applies to the first call, not to switched or outgoing connections. A recall of an external station is not immediately intercepted when the destination station is busy; instead, call waiting is activated.
 •   Intercept if incomplete or invalid number dialed
    When an incorrect station number was dialed, the system determines whether the call should be intercepted or released. Calls are always intercepted with pseudo-DID.
 •   Intercept if no number dialed
    If no station number is dialed within a timeout, the system determines whether the call should be intercepted or released. If an intercept position has not been configured, the interception follows the call assignment per trunk.
 •   Intercept with Serial FWD
    It is not possible to chain calls for forwarding; an attempt to initiate this procedure is rejected on activation. For example: if a station has activated external call forwarding and the call destination has also forwarded its calls, you have a chained calls situation. This is not allowed by the system. If this flag is turned on, these calls are intercepted.
 •   Codelock Diversion
    If the lock code for a station is active, and a trunk group code is dialed from that station, the call is immediately forwarded to the intercept destination. The Codelock Diversion function is set individually for each station through the Flags screen in the Set up Station Parameters.
One intercept position can be configured for Day operation. During Night Service, the same destination or a different destination can be configured as the intercept position.

Dependencies/Restrictions  

 Subject  
 Dependency/Restriction  
Hunt group  
Intercepts cannot extend beyond a hunt group; the call is forwarded to the first hunt group station and always remains in the hunt group.  
Release  
Calls with the service ID data service (ISDN message) are released, not intercepted.  
Incomplete dialing  
Not evaluated in the case of a central intercept position.  
Tenant system  
When a tenant service is configured, users can only configure intercepts on a cross-system basis. This means that intercept no answer (for example) applies to all system users.
