Parameter Description
 During an existing call, if a call comes in (call waiting),
pressing the flash button places the active call on hold and
answers the waiting call; pressing flash again toggles
between these two calls.
 [1] Sequence 1 = Sequence of flash button with digit:

Flash + 1: holds a call or toggles between two existing
calls

Flash + 2: makes a call transfer.

Flash + 3: makes a three-way conference call (if the Three-
Way Conference feature is enabled, i.e., the parameter
Enable3WayConference is set to 1 and the parameter
3WayConferenceMode is set to 2).
 [2] Sequence 2 = Sequence of flash button with digit:

Flash only: Places a call on hold.

Flash + 1:
1) When the device handles two calls (an active and a held
call) and this key sequence is dialed, it sends a SIP BYE
message to the active call and the previously held call
becomes the active call.
2) When there is an active call and an incoming waiting
call, if this key sequence is dialed, the device disconnects
the active call and the waiting call becomes an active call.

Flash + 2: Places a call on hold and answers a call-waiting
call, or toggles between active and on-hold calls.

Flash + 3: Makes a three-way conference call. This is
applicable only if the Enable3WayConference parameter is
set to 1 and the 3WayConferenceMode parameter is set to
2. Note that the settings of the ConferenceCode parameter
is ignored.

Flash + 4: Makes a call transfer.
Note: The parameter is applicable only to FXS interfaces.
