Call Keys 
 
Implementing features, see also Manager E Call Keys

Definition  
Users can program up to ten call keys (together with multiple subscriber numbers) on an optiPoint telephone. These keys are used for incoming and outgoing calls. The call keys are assigned to trunks virtually; that is, the trunks are not permanently assigned to a specific key (like trunk group keys). When performing an outgoing external seizure, users press a call key to seize a trunk group. When users connect without a call key, an available call key is automatically seized, depending on the trunk group. With incoming calls, an available call key corresponding to the trunk group is also assigned.
The call keys should be viewed as temporary trunk keys that allow quick access to the following features:
 •   Answering and signaling calls and recalls
 •   Toggle/Connect
 •   Cancel consultation
 •   Pickup

Operation  
If the default station templates are in effect, this feature can only be used on display telephones.
 •   Answering and signaling initial calls and recalls: The Call key can also operate as a Loop key. That is, a user can have two or more Call keys on his or her telephone representing the same trunks. The first incoming call will be presented to the first idle Call key; the second call to the next idle Call key, and so on. The call can be transferred using the Consultation Hold function using a feature button or with the dialog keys. Unanswered calls or unretrieved parked calls recall the station on the Call key and can be answered again on the Call key (Common hold: still assigned to that Call key)
 •   Toggle/Connect: If a user has an appearance of several Trunk keys on his or her telephone, the user can toggle between any of the Call keys by pressing the desired Call key. The first trunk is placed on Consultation Hold at the station. Any subsequent depression of another Call key places the last call on Consultation Hold at that telephone. If the user goes on-hook at any point, the last held party immediately recalls per the Consultation Hold procedure.
 •   Pickup: An incoming call ringing on a Call key can be picked up from another station via the feature Call Pickup - Group or via Call Pickup - Directed.
    Conversely, if a user with a Call key on the telephone, picks a trunk call from another station, the trunk appears on the Call key.
 •   Placing a call: The user presses a Call key. The user is presented with simulated dial tone if LCR is in effect or, if not, CO dial tone.
 •   Receiving a call: An incoming call is signalled audibly and visually at the station. The display shows the trunk group name. If caller ID is available, the user display will indicate the calling party's caller ID number. Calling party name is not available. The user presses the flickering key to answer the call. The LED of the Call key remains lit.
