InterCom Announcement/Hands-Free
The InterCom function enables an announcement to system phones (one phone or group) from any internal phone without someone having to actively receive a call (for example, in a doctor's office).
Furthermore, the caller's system phone can be programmed to switch on the microphone in addition to the loudspeaker (hands-free) so that a person nearby can speak with the caller using this intercom system.
InterCom announcement and InterCom hands-free are carried out as follows:
A single system phone or a group is called using the InterCom function.
* Note: If a group is called using the InterCom function, all system phones of the group that have given the InterCom permission and are ready to take calls will be called. The group status (logged in, logged out) will not be taken into account. Hands-free calling is not possible in the case of an InterCom call to a group.
After a few rings, the system phone/system phones of the group members automatically pick up the call.
Announcement or hands-free calling is executed.
* Note: Announcement or hands-free calling is limited to 120 seconds due to security reasons in order to prevent possible misuse of this function (for example, eavesdropping from remote rooms).
After 120 seconds has elapsed, the connection is automatically interrupted unless the system phone receiver is picked up during this time.
Requirements:
System phone, that supports InterCom (optional, see the phone manual)
Proceed as follows for configuration:
Switching the InterCom permission for the involved internal phones on.
-Using the Configuration Manager (page Subscriber (scr.) > Properties > Settings)
If necessary, assigning a function key for InterCom on the system phone (optional, see the phone manual).
