How InterCom Announcement Works

The InterCom announcement process runs as follows:

•

According to the InterCom destination, either a single system telephone or all system telephones in a group that have the InterCom function are called.

Note: The only system telephones in the group that are called are those which are available for a conversation, e.g. those that are not busy. This means the individual members of the group do not need to be logged into the group. They are still called if they are logged off from the group.

•

Depending on InterCom destination is involved, after a short ring, either a single system telephone or all the system telephones in the group automatically take the call.

•

The announcement is performed.

Note: For security reasons, the announcement is limited to 120 seconds to prevent possible misuse of this function (for example, eavesdropping from distant rooms).

•

At the end of 120 seconds the connection is automatically interrupted. If the InterCom destination is a single system telephone, the connection can be maintained by picking up the system telephone's receiver before the 120 seconds elapses.
