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 either outside caller hangs up. Optionally, you can rejoin the Conference and end it whenever you choose.
There are two methods for setting up Tandem Trunking. Your Communications Manager can tell you which method is available
to you.
Method A
To make a line-to-line Conference:
1. Set up first outside call.
This can be a call you placed or answered.
2. Press CONF.
3. Set up second outside call.
4. Press CONF twice.
You now have a Conference between you and the two outside parties.
5. FUNCTION KEY (Transfer).
OR
5. HOLD + #8.
You drop out of the call and leave the outside callers talking to each other.
The line keys for the calls blink as long as the Unsupervised Conference continues. If one of your outside
callers hangs up, the Conference ends.
To return to the tandem call:
1. Press flashing line key.
You must have a line key to be able to rejoin the Conference. Press Transfer key or HOLD + #8 to reinstate
the Conference.
If one of the callers hangs up, you continue talking to the remaining caller.
To end the line-to-line Conference:
1. Press flashing line key to return to the Conference.
2. TALK to hang up.
Method B (Requires a FUNCTION KEY [Transfer])

This can be a call you placed or answered.

You can also use the Forced Trunk Disconnect feature, if it is enabled, by pressing a line key + *3.

Trunk Queuing

When you try to place an outside call and hear busy tone from your own phone system, you don't have to hang up and try again
later. Use Trunk Queuing to leave a request for the busy line to call you when it's free. Just answer when Trunk Queuing rings
you back and dial your call again. If you prefer, use Trunk Camp On to wait for the busy line without hanging up. With Trunk
Camp On, you'll be able to use the line the moment it's available.
