Defines the key sequence with the flash button:

'Flash only' (default) = uses only the phone's Flash button. There are
three scenarios:

During an existing call, if the user presses Flash, the call is put on
hold, a dial tone is heard and the user is able to initiate a second
call. Once the second call is established, on-hooking transfers the
first (held) call to the second call.

During an existing call, if the user presses Flash, the call is put on
hold and a dial tone is heard. The user can initiate a second call
and establish a 3-way conference by again pressing Flash after
the second call is initiated.

During an existing call, if a call comes in (call waiting), pressing
Flash puts the active call on hold and answers the waiting call;
pressing Flash again toggles between these two calls.

'Flash + digits sequence' = Flash button with a key sequence:
This feature has been updated and now includes three different types:
Type 1:

Flash + 1 holds a call or toggles between two existing calls

Flash + 2 makes a call transfer

Flash + 3 establishes a 3-way conference
Type 2:

Flash – holds a call

Flash + 2 toggles between two existing calls

Flash + 3 establishes a 3-way conference

Flash + 4 makes a call transfer
Type 3:

Flash + 1 toggles between two existing calls

Flash + 2 holds a call

Flash + 4 establishes a 3-way conference

'Send Flash Hook Via SIP' = you can modify the SIP INFO message
that is sent upon Flash. You can change the Content Type header
field and Message Body field.
Note: This parameter appears only in 'Advanced' mode.
When the key sequence is set to 'Send Flash Hook Via SIP', you can
modify the Content Type header field of the SIP INFO message.
For example: "application/broadsoft; version = 1.0"
Note: This parameter appears only when the 'Flash keys sequence style'
field is set to 'Send Flash Hook Via SIP'.
