Central Caller List
The phone numbers of unaccepted calls are stored in the caller list on the system phone (optional, see phone manual). As soon as a connection (incoming or outgoing) has been made to a caller, the corresponding phone number is automatically deleted from the caller list.
If a group call occurred and if the central caller list for groups is enabled, the phone number is also deleted from the caller lists of the other members of the group.
*Note: Group-wide deletion does not occur if the person calling back has already deleted his caller list or has been called again by the same caller on his subscriber number.
Requirements:
All group members are system phones, that support the central caller list (optional, see the phone manual)
Proceed as follows for configuration:
Switching the central caller list for the involved groups on.
Using the Configuration Manager (Groupes > Propriétés > Paramètres)
