Step Calling
When you make an Intercom call and receive a busy signal or no
answer, Step Calling lets you call the other extensions, in ascending
order, by just dialing '#'. For example, if extension 12 is busy, Step
Calling tries extension 13. If there is no answer at extension 13, Step
Calling tries extension 14, and so on. Step Calling is cancelled if it
reaches an extension that is not installed.
To initiate a Step Call:

Tandem Trunking

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 you reen-
ter the conversation and hang up the call or either party terminates the
call. 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
