Call Waiting; Supervisory Override - Samsung SGH-A997 User Manual

Call Waiting

While on an EPTT call you cannot receive an incoming EPTT
call. You will be notified with a Missed Call message after
finishing the original call.
While on an EPTT call you are notified of incoming cellular
calls. Accepting the incoming cellular call places the EPTT
call on hold. The EPTT call will continue after the cellular call
ends. Rejecting the incoming cellular call forwards it to
voicemail.
If you are on a cellular call, you are notified of missed EPTT
calls when you terminate the cellular call. You can Dismiss
the message or press the EPTT key to make an EPTT call to
the caller.

Supervisory Override

The Supervisory Override feature allows a designated
supervisor to take the floor (and start speaking) any time
during a group call, even when someone else is speaking.
Only an administrator can assign a supervisor. The
supervisor can see a special supervisor icon that is displayed
next to the group name. Group members only see the icon
next to the group supervisor's name in the group member
list.
If you are designated as a supervisor, you can simply use the
EPTT call button to take the floor any time and start
speaking. Likewise, if you are not a supervisor, your control
of the floor can be overridden at any time by a supervisor.
