Selective Seizure of a DID Number Using a MUSAP Key 
 

Definition  
For users to seize one of the system DID numbers for outgoing calls, they must either use a procedure or configure a multiple station appearance (MUSAP) key. This key is assigned a DID number in the system. However, pressing this key is not sufficient for seizure. The trunk group, trunk, or Prime Line must be suffix-dialed for seizure to occur.
For incoming calls, the MUSAP key functions as a call key. The LED is activated in the same way as for trunk keys, call keys, or DSS keys, depending on the status of the trunk key to which it is connected. Features such as toggle and consultation hold are possible.
For outgoing calls, the MUSAP key functions as a call key after the external seizure is completed.
A MUSAP key is used as a target location for incoming DID calls from the public network. The key can also be used as a target for incoming calls from a CorNet location. If the station is assigned a MUSAP key, the DID number associated with the key is sent to the ISDN Public Network on BRI and PRI outgoing calls.
Up to 10 MUSAP keys can be programmed on the same station to support rollover buttons for additional calls to the same DID number. A maximum of 10 MUSAP and/or call keys can be programmed on an optiPoint 500.

MUSAP keys do not seize trunk groups directly. After you press the key, you must dial the trunk group separately.
