This feature is useful when Tunneling or Fast Connect are used. The Voice
channel in the egress gateway is opened immediately after sending an ALERT
message. If this is not the appropriate procedure, you can set this parameter to
“1” to open voice channel only after CONNECT is sent.
Using Hunt
Groups TrunkGroup_x = a-b, <starting number>
IsUseFreeChannel
PSTNPrefix = <prefix>, <Hunt Group ID>
AddTrunkGroupAsPrefix
range

0
This feature can be used to define a group of gateway ports, called hunt groups.
For example:
• TrunkGroup_1 = 1-2,100
• TrunkGroup_1 = 3,200
• TrunkGroup_2 = 4,300
To use the hunt groups you must also define "IsUseFreeChannel=1", and define
routing rules, using "PSTNPrefix" parameter.
The routing IP to Telephone rules define, per called number prefix, the Hunt
Group ID where the call will be sent to. For example:
• PSTNPrefix = 101,1
Incoming IP to telephone call, with called number starting with 101 will select a
free channel from 1st Hunt group.
"AddTrunkGroupAsPrefix = 1" can be used when incoming Telephone to IP call
should be treated differently according to received hunt group. If this feature is
enabled the Hunt group ID is added to called number as a prefix. The number
manipulation and routing (Prefix=) rules will apply to the new destination number.
Note: When using Trunk groups do not use "ChannelList" or "Channel2Phone"
parameters.
