Description
Tandem Trunking allows an extension user to join two outside callers in a trunk-to-trunk Confer-
ence. (Depending on your software level, it may be possible to conference 3 or more trunks with
Tandem Trunking.) The extension user can then drop out of the call, leaving the trunks in an Unsu-
pervised Conference. The extension user that established the Conference is not part of the conversa-
tion. The Conference continues until either outside party hangs up. In addition, the extension user
that set up the Conference can end the tandem call at any time.
The number of simultaneous Conference calls is limited by the number of Conference circuits in the sys-
tem. Due to this fact, the maximum number of Conference calls cannot exceed the limits deÞned in the
above table.
