Thanks to the 3-way conference intercom feature, you could make and receive another

intercom call even while you are already having an intercom conversation.

All three participants (A, B & C) could receive Bluetooth mobile phone calls even while the

conference intercom is in progress.

4-Way Conference Intercom

A 4-way conference intercom conversation can be established by adding one more participant

to a 3-way conference intercom.

1. In the above case of 3-way conference intercom, another participant D who is an Intercom

Friend of (C), could join the conference intercom by establishing a new intercom

connection with your Second Intercom Friend (C) and form a 4-way conference intercom.

2. To do this, (C) has to make an intercom call to (D) or receive an intercom call from (D),

while having a 3-way intercom.

The rule of thumb of conference intercom is that one can have two active intercom

connections at the same time.

All four participants (A, B, C & D) can receive Bluetooth mobile phone calls even while the

conference intercom is in progress.
