2 Multiparty or Conference Calls
The multiparty or 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 multiparty call can only be set up when you have one active call
and one call on hold, both calls having been answered. Once a
multiparty call is set up, calls may be added, disconnected or
separated (that is, removed from the multiparty call but still
connected to you) by the person who set up the multiparty call.
The maximum callers in a multiparty call is five. Once started, you
are in control of the multiparty call, and only you can add calls to the
multiparty call.
