14. THREE-WAY CONFERENCE
INTERCOM
14.1 Start Three-way Intercom
You (A) can have a three-way conference intercom
with two other SPH10H friends (B & C) by establishing
two intercom connections at the same time. While
a three-way conference intercom is in progress,
mobile phone connection of all three participants
would be temporarily disconnected, but as soon as
the conference intercom terminates or one of the
participants leaves the intercom, all mobile phones
would be automatically reconnected. During the
conference intercom, if you have an incoming mobile
phone call, terminate the conference intercom to
automatically reconnect the mobile phone and
receive the call.
