Tandem Trunking lets you set up a Conference with two outside
callers and then drop out of the call - leaving the callers talking in an
Unsupervised Conference. Once you drop out you are not part of the
conversation. The Unsupervised Conference continues until either out-
side caller hangs up. Optionally, you can rejoin the Conference and
end it whenever you choose.
If you are a dispatcher for outside service people, for example, you
can use Tandem Trunking to put two of your service people in touch:
●Answer a call from one service person.
●Place a call to the second service person.
●Set up the line-to-line Conference.
●Drop out of the call.
