InterCom Announcement / InterCom Handsfree Procedure
InterCom Announcement/Handsfree
The InterCom function enables an announcement to a system telephone (COMfortel 1100/
1500/2500/2500 AB/VoIP 2500 AB) from any internal telephone without someone having to
actively receive a call (for example, in a doctor's office).
Furthermore, the caller's system telephone can be programmed to switch on the microphone
in addition to the loudspeaker (handsfree) so that a person nearby can speak with the caller
using this intercom system.
InterCom Announcement / InterCom Handsfree Procedure
InterCom announcement and InterCom handsfree are carried out as follows:
• A system telephone is called using the InterCom function.
• After a few rings, the system telephone automatically picks 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 telephone receiver is picked up during this time.
Initiating InterCom Announcement/Handsfree
Initiation can be carried out as follows:
• Using a character string on the internal telephone
