Description
Tandem Trunking allows an extension user to join two or more outside callers in a trunk-to-trunk
Conference. The extension user can then drop out of the call, leaving the trunks in an Unsupervised
Conference. The extension user that established the Conference is not part of the conversation. 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 Conference calls is limited by the number of Conference circuits in the system. Due to
this fact, the maximum number of Conference calls cannot exceed the limits defined in the above table.
