Valid Range and Description
ChannelSelectMode
[Channel Select Mode]
Defines common rule of port allocation for IP to TEL calls.
• 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
[Trunk Group Settings]
Defines rules for port allocation for specific Trunk Groups, if such rule doesn’t exist,
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
[Add Trunk Group ID as Prefix]
0 = not used
1 = For TelIP 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
[Add Trunk ID as Prefix]
0 = Don’t add (default)
1 = Add trunk ID number (single digit in the range 1 to 8) as a prefix to the called
phone number for TelIP incoming calls.
This option can be used to define various routing rules.
ReplaceEmptyDstWithPortNu
mber
[Replace Empty Destination
with Port Number]
0 = Disabled (default).
1 = Enabled, Internal channel number is used as a destination number if called
number is missing.
Note: Applicable only to TelIP 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
ber
0 = Do not change the Calling Number (default).
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
er
0 = Do not change the Called Number (default).
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.
