SLT Conference
A single line telephone (SLT) user can be used to initiate a three-way conference with any
combination of CO line or internal users, as well as incoming or outgoing.
An SLT user can toggle between two calls, while maintaining private conversations with each
of the other two parties.
OPERATION / SETUP
To set up a conference from an SLT phone:
1. While on a call, perform a hook-flash.
2. An intercom dial tone sounds, the current call is placed on Exclusive Hold (see "Hold"
on page 1-184), and the recall timer is activated.
3. Place the second call.
4. Perform a hook-flash to reconnect to the first call.
5. Within the next two seconds, perform a hook-flash again to join all three participants
(including the initiator), and establish the conference.
