[FirstCallWaitingToneID] Defines the index of the first Call Waiting Tone in the CPT file.
This feature enables the called party to distinguish between
different call origins (e.g., external versus internal calls).
There are three ways to use the distinctive call waiting tones:
 Playing the call waiting tone according to the SIP Alert-Info
header in the received 180 Ringing SIP response. The value of
the Alert-Info header is added to the value of the
FirstCallWaitingToneID parameter.
 Playing the call waiting tone according to PriorityIndex in the
ToneIndex table parameter.
 Playing the call waiting tone according to the parameter
“CallWaitingTone#' of a SIP INFO message.
The device plays the tone received in the 'play tone
CallWaitingTone#' parameter of an INFO message plus the value
of the parameter minus 1.
The valid range is -1 to 1,000. The default is -1 (i.e., not used).
Note:
 The parameter is applicable only to analog interfaces.
 It is assumed that all Call Waiting Tones are defined in
sequence in the CPT file.
 SIP Alert-Info header examples:
Alert-Info:<Bellcore-dr2>
Alert-Info:<http://…/Bellcore-dr2> (where "dr2" defines call
waiting tone #2)
 The SIP INFO message is according to Broadsoft's application
server definition. Below is an example of such an INFO
message:
