Conference Add/Split/Join/DropIf you initiate a conference with two or more parties, you can continue to add outside
callers to conference; or you and another member of the conference can leave (Split)
the conference for a private conversation. During this time, other conference members
remain connected.
You can then Join both of you back into the conference, or you can Drop (disconnect)
the member you are connected to. This feature is performed with Soft Keys if you
have a LCD phone or with a Split button programmed on one of your Programmable
Feature Buttons.
This feature also works for remote stations which are connected through Strata Net
QSIG.
Important! You must be a conference master to perform the Add, Split and Drop
features. The conference master is the person that initiates the
conference call. If that person drops from the conference, the first
person added to the conference becomes the conference master.
