The following example demonstrates three-way conferencing using the device's local, on-
board conferencing feature. In the example, telephone "A" connected to the device
establishes a three-way conference call with two remote IP phones, "B" and "C":
1. A establishes a regular call with B.
2. A places B on hold, by pressing the telephone's flash-hook button and the number "1"
key.
3. A hears a dial tone and then makes a call to C.
4. C answers the call.
5. A establishes a three-way conference call with B and C, by pressing the flash-hook
button and the number "3" key.


pattern (e.g., hook flash) that upon detection generates the conference call.
•
From the 'Flash Keys Sequence Style' drop-down list (FlashKeysSequenceStyle),
select Sequence 1 or Sequence 2 to use the flash + 3 key-combination to create
