Table 6-5: Number Manipulation and Routing Parameters (continues on pages 115 to 121)

	ini File Field Name		Valid Range and Description
	Web Parameter Name*
	ChannelSelectMode	Defines common rule of port allocation for IP to TEL calls.
	[Channel Select Mode]	• 0 = By phone number - Select the gateway port according to the called number
		(refer to the note below).
		• 1 = Cyclic Ascending - Select the next available channel in an ascending cycle
		order. Always select the next higher channel number in the Trunk Group. When
		the gateway reaches the highest channel number in the Trunk Group, it selects
		the lowest channel number in the Trunk Group and then starts ascending again
		(default).
		• 2 = Ascending - Select the lowest available channel. Always start at the lowest
		channel number in the Trunk Group and if that channel is not available, select
		the next higher channel.
		• 3 = Cyclic Descending - Select the next available channel in descending cycle
		order. Always select the next lower channel number in the Trunk Group. When
		the gateway reaches the lowest channel number in the Trunk Group, it selects
		the highest channel number in the Trunk Group and then start descending
		again.
		• 4 = Descending - Select the highest available channel. Always start at the
		highest channel number in the Trunk Group and if that channel is not available,
		select the next lower channel.
		• 5 = Number + Cyclic Ascending – First select the gateway port according to the
		called number (refer to the note below). If the called number isn’t found, then
		select the next available channel in ascending cyclic order. Note that if the
		called number is found, but the port associated with this number is busy, the call
		is released.
		Note: The internal numbers of the gateway’s B-channels are defined by the
		‘TrunkGroup_x’ parameter (under ‘Phone Number’).
	TrunkGroupSettings	Defines rules for port allocation for specific Trunk Groups, if such rule doesn’t exist,
	[Trunk Group Settings]	the global rule defined by ChannelSelectMode applies.
		a, b
		a = Trunk Group ID number
		b = Channel select mode for that Trunk Group.
		Available values are identical to those defined by the ChannelSelectMode parameter.
	AddTrunkGroupAsPrefix	0 = not used
	[Add Trunk Group ID as Prefix]	1 = For Tel IP incoming call, Trunk Group ID is added as prefix to destination phone
		number. Applicable only if trunk group ID are configured.
		Can be used to define various routing rules.
	AddPortAsPrefix	0 = Don’t add (default)
	[Add Trunk ID as Prefix]	1 = Add trunk ID number (single digit in the range 1 to 8) as a prefix to the called
		phone number for Tel	IP incoming calls.
		This option can be used to define various routing rules.
	ReplaceEmptyDstWithPortNu	0 = Disabled (default).
	mber	1 = Enabled, Internal channel number is used as a destination number if called
	[Replace Empty Destination	number is missing.
	with Port Number]	Note: Applicable only to Tel		IP calls, if called number is missing.
	CopyDestOnEmptySource	0 = Leave Source Number empty (default).
		1 = If the Source Number of an incoming Tel to IP call is empty, the Destination
		Number is copied to the Source Number.
	AddNPIandTON2CallingNum	0 = Do not change the Calling Number (default).
	ber	1 = Add NPI and TON to the Calling Number of incoming (Tel to IP) ISDN call.
		For example: After receiving a Calling Number = 555, NPI = 1 and TON = 3, the
		modified number is going to be 13555. This number can later be used for
		manipulation and routing purposes.
	AddNPIandTON2CalledNumb	0 = Do not change the Called Number (default).
	er	1 = Add NPI and TON to the Called Number of incoming (Tel to IP) ISDN call.
		For example: After receiving a Called Number = 555, NPI=1 and TON = 3, the
		modified number is going to be 13555. This number can later be used for
		manipulation and routing purposes.
