CONFERENCE CALLS
The conference service provides you with the ability
to have a simultaneous conversation with more than
one caller, if your network service provider supports
this feature. A conference call can only be set up when
you have one active call and one call on hold, both
calls having been answered. Once a conference call is
set up, calls may be added, disconnected or separated

connected to you) by the person who set up the
conference call. These options are all available from
