12. FOUR-WAY CONFERENCE INTERCOM
12.1 Start Four-way Intercom
You can have four-way conference intercom with three other EXPAND users by adding one more intercom participant to
the three-way intercom. While you are having three-way intercom as above in section 14.1, a new participant (D), who is
an intercom friend of your intercom friend (C), may join the conference intercom by making an intercom call to your
intercom friend (C). Please note that in this case, the new participant (D) is an intercom friend of (C), not of you (A).
