ini File Field Name		Valid Range and Description
Web Parameter Name*
OutOfBandDTMFFormat	The exact method to send out-of-band DTMF digits
[Out-of-Band DTMF Format]	1 = INFO format (Nortel)
	2 = INFO format (Cisco) - (default)
	3 = NOTIFY format <draft-mahy-sipping-signaled-digits-01.txt>
	Note 1: To use out-of-band DTMF, set “IsDTMFUsed=1”.
	Note 2: When using out-of-band DTMF, the “DTMFTransportType” parameter is
	automatically set to 0, to erase the DTMF digits from RTP path.
DisableAutoDTMFMute	Enables / disables the automatic mute of DTMF digits when out-of-band DTMF
	transmission is used.
	0 = Auto mute is used (default).
	1 = No automatic mute of in-band DTMF.
	When ‘DisableAutoDTMFMute=1’, the DTMF transport type is set according to the
	parameter ‘DTMFTransportType’ and the DTMF digits aren’t muted if out-of-band
	DTMF mode is selected (’IsDTMFUsed =1’). This enables the sending of DTMF digits
	in-band (transparent of RFC 2833) in addition to out-of-band DTMF messages.
	Note: Usually this mode is not recommended.
MaxActiveCalls	Defines the maximum number of calls that the gateway can have active at the same
[Max Number Of Active Calls]	time. If the maximum number of calls is reached, new calls are not established.
	The default value is max available channels (no restriction on the maximum number of
	calls). The valid range is 1 to 240.
MaxCallDuration	Defines the maximum call duration in minutes. If this time expires, both sides of the call
[Max Call Duration]	are released (IP and Tel).
	The valid range is 0 to 120. The default is 0 (no limitation).
EnableBusyOut	0 = Not used (default)
[Enable Busy Out]	1 = Enable busy out
	If Proxy is not responding (according to the Proxy keep alive mechanism) or if there is a
	failure in the network, and if fallback isn’t enabled (IsFallbackUsed=0), all E1/T1 trunks
	are automatically put out of service by sending a remote alarm (AIS) or Service Out
	message for T1 PRI trunks that support these messages (NI-2, 4/5-ESS, DMS-100 and
	Meridian). Note that behavior varies between different protocol types.
EnableDigitDelivery2IP	0 = Disabled (default).
[Enable Digit Delivery to IP]	1 = Enable digit delivery to IP.
	The digit delivery feature enables sending of DTMF digits to the destination IP address
	after the Tel IP call was answered.
	To enable this feature, modify the called number to include at least one ’p’ character.
	The gateway uses the digits before the ‘p’ character in the initial Invite message. After
	the call was answered the gateway waits for the required time (# of ‘p’ * 1.5 seconds)
	and then sends the rest of the DTMF digits using the method chosen (in-band, out-of-
	band).
	Note: The called number can include several ‘p’ characters (1.5 seconds pause).
	For example, the called number can be as follows: pp699, p9p300.
EnableDigitDelivery	The digit delivery feature enables sending of DTMF digits to the Gateway’s B-channel
[Enable Digit Delivery to Tel]	after the call is answered.
	0 = Disabled (default).
	1 = Enable Digit Delivery feature for Mediant 2000 (two stage dialing).
	Note: For incoming IP	Tel calls, if the called number includes the characters ‘w’ or ‘p’,
	the Mediant 2000 Gateway places a call with the first part of the called number, and
	plays DTMF digits after the call is answered. If the character ‘p’ (pause) is used, the
	Mediant 2000 waits for 1.5 seconds before playing the next DTMF digit. If the character
	‘w’ is used, the Mediant 2000 waits for detection of dial tone before it starts playing
	DTMF digits. The character ‘w’ can appear once in the called number, and must
	precede any ‘p’ character. The ‘p’ character can appear several times.
	For example: if the number “1007766p100” is defined as the called number, the
	Mediant 2000 places a call with 1007766 as the destination number, then, after the call
	is answered, it waits for 1.5 seconds and plays the rest of the number (100) as DTMF
	digits.
	Other examples: 1664wpp102, 66644ppp503, 7774w100pp200.
