Call Setup Rules Set
ID
[PREFIX_CallSetupR
ulesSetId]
Assigns a Call Setup Rule Set ID to the routing rule. The device performs the
Call Setup rules of this Set ID if the incoming call matches the characteristics
of the routing rule. The device routes the call to the destination according to
the routing rule's configured action only after it has performed the Call Setup
rules.
By default, no value is defined.
For configuring Call Setup rules, see ''Configuring Call Setup Rules'' on page
287.
Forking Group
[PREFIX_ForkingGro
up]
Defines a Forking Group number for the routing rule. This enables forking of
incoming Tel calls to multiple IP destinations. The device sends simultaneous
INVITE messages and handles multiple SIP dialogs until one of the calls is
answered. When a call is answered, the other calls are dropped.
By default, no value is defined.
If all matched routing rules belong to the same Forking Group number, the
device sends an INVITE to all the destinations belonging to this group. If
matched routing rules belong to different Forking Groups, the device sends
the call to the Forking Group of the first matched routing rule. If the call cannot
be established with any of the destinations associated with the Forking Group
and alternative routing is enabled, the device forks the call to the Forking
Group of the next matched routing rules, as long as the Forking Group is
defined with a higher number than the previous Forking Group. For example:
 Table index entries 1 and 2 are defined with Forking Group "1", and index
entries 3 and 4 with Forking Group "2": The device first sends the call
according to index entries 1 and 2, and if unavailable and alternative
routing is enabled, sends the call according to index entries 3 and 4.
 Table index entry 1 is defined with Forking Group "2", and index entries 2,
3, and 4 with Forking Group "1": The device sends the call according to
index entry 1 only and ignores the other index entries even if the
destination is unavailable and alternative routing is enabled. This is
because the subsequent index entries are defined with a Forking Group
number that is lower than that of index entry 1.
 Table index entry 1 is defined with Forking Group "1", index entry 2 with
Forking Group "2", and index entries 3 and 4 with Forking Group "1": The
device first sends the call according to index entries 1, 3, and 4 (all
belonging to Forking Group "1"), and if the destination is unavailable and
alternative routing is enabled, the device sends the call according to index
entry 2.
 Table index entry 1 is defined with Forking Group "1", index entry 2 with
Forking Group "3", index entry 3 with Forking Group "2", and index entry 4
with Forking Group "1": The device first sends the call according to index
entries 1 and 4 (all belonging to Forking Group "1"), and if the destination
is unavailable and alternative routing is enabled, the device sends the call
according to index entry 2 (Forking Group "3"). Even if index entry 2 is
unavailable and alternative routing is enabled, the device ignores index
entry 3 because it belongs to a Forking Group that is lower than index
entry 2.
Notes:
 To enable Tel-to-IP call forking, set the 'Tel2IP Call Forking Mode'
(Tel2IPCallForkingMode) parameter to Enable.
 You can configure the device to immediately send the INVITE message to
the first member of the Forking Group (as in normal operation) and then
