the lower cost. However, if the average call duration is more

33.6 Configuring IP Group Sets
The IP Group Set table lets you configure up to 51 IP Group Sets. An IP Group Set is a
group of IP Groups used for load balancing of calls, belonging to the same source, to a call
destination (i.e., IP Group). Each IP Group Set can include up to five IP Groups (Server-
type and/or Gateway-type only). The chosen destination IP Group for each call depends on
the configured load-balancing policy, which can be Round Robin, Random Weights, or
Homing (for more information, see the table's description, later in this section).
Alternative routing within the IP Group Set is also supported, whereby if a chosen
destination IP Group responds with a reject response that is configured as a reason for
alternative routing (see Configuring SIP Response Codes for Alternative Routing Reasons
on page 668) or doesn't respond at all (i.e., keep-alive with its' associated Proxy Set fails),
the device attempts to send the call to another IP Group in the IP Group Set (according to
the load-balancing policy). For enabling Proxy Set keep-alive, see Configuring Proxy Sets
on page 346.
An example of round-robin load-balancing and alternative routing: The first call is sent to IP
Group #1 in the IP Group Set, the second call to IP Group #2, and the third call to IP Group
#3. If the call sent to IP Group #1 is rejected, the device employs alternative routing and
sends it to IP Group #4.
To implement call load-balancing by IP Groups, you need to assign the IP Group Sets to
the desired routing rules in the IP-to-IP Routing table. The 'Destination Type' of these
routing rules must also be configured to IP Group Set. For more information, see
Configuring SBC IP-to-IP Routing Rules on page 656.
IP Group Sets are configured using two tables with parent-child type relationship:
Parent table: IP Group Set table, which defines the name and load-balancing policy
of the IP Group Set.
Child table: IP Group Set Member table, which assigns IP Groups to IP Group Sets.
You can assign up to five IP Groups per IP Group Set.
The following procedure describes how to configure IP Group Sets through the Web
interface. You can also configure it through other management platforms:
IP Group Set Table: ini file (IPGroupSet) or CLI (configure voip > )
IP Group Set Member Table: ini file (IPGroupSetMember) or CLI (configure voip > )
To configure an IP Group Set:
5. Open the IP Group Set table (Setup menu > Signaling & Media tab > SBC folder >
Routing > IP Group Set).
