Intercom is an auto answer and loud speaking function at the receiving extension. To get the Intercom working the telephones must support the intercom feature.

A typical application of the intercom is a chief-secretary or a doctor-nurse setup. The chief/ doctor has a Push2Talk or Intercom button on his Telephone. The secretaries/nurse telephone has the Intercom enabled to answer automatically via the loudspeaker. the chief announces: “next guest/patient please…”. The intercom windows consist of a list panel and a configuration panel.
