CHAPTER 34 Routing SBC
Parameter
■ [4] Hunt Group = Used for call center survivability. For more
information, see Configuring Call Survivability for Call
■ [5] Dial Plan = (For Backward Compatibility Only - see Note
below) The IP destination is determined by a Dial Plan index of
the loaded Dial Plan file. The syntax of the Dial Plan index in the
Dial Plan file is as follows: <destination / called prefix
number>,0,<IP destination>
Note that the second parameter "0" is ignored. An example of a
configured Dial Plan (# 6) in the Dial Plan file is shown below:
[ PLAN6 ]
200,0,10.33.8.52 ; called prefix 200 is routed to destination
10.33.8.52
201,0,10.33.8.52
300,0,itsp.com ; called prefix 300 is routed to destination
itsp.com
Once the Dial Plan is defined, you need to assign it (0 to 7) to the
routing rule as the destination in the 'Destination Address' para-
meter, where "0" denotes [PLAN1], "1" denotes [PLAN2], and
so on.
■ [7] LDAP = LDAP-based routing. Make sure that the Routing
Policy assigned to the routing rule is configured with the LDAP
Server Group for defining the LDAP server(s) to query.
■ [8] Gateway = The device routes the SBC call to the Tel side
(Gateway call) using an IP-to-Tel routing rule in the IP-to-Tel
Routing table (see Configuring IP-to-Tel Routing
to-Tel routing rule must be configured with the same call
matching characteristics as this SBC IP-to-IP routing rule. This
option is also used for alternative routing of an IP-to-IP route to
the PSTN. In such a case, the IP-to-Tel routing rule must also be
configured with the same call matching characteristics as this
SBC IP-to-IP routing rule.
Note:
✔
If you configure the parameter to Gateway for a rule that is
used for alternative routing (i.e., 'Alternative Route Options'
parameter is configured to any value other than Route
Row), the device utilizes two DSP session resources. One
session resource is for the new Gateway route and one for
the initial SBC session used for the incoming leg.
✔
When the device uses this rule that is configured to
Gateway and the 'Alternative Route Options' parameter is
configured to Route Row, it ignores all other matching rules
listed below this rule in the IP-to-IP Routing table.
■ [9] Routing Server = Device sends a request to a third-party
routing server for an appropriate destination (next hop) for the
matching call.
