The flowchart below illustrates the SBC process:
Figure 31-1: Routing Process
31.3 User Registration
To allow registrations to traverse the SBC, the device must be configured with at least one
User-type IP Group. These IP Groups represent a group of user agents that share the
following characteristics:
Perform registrations and share the same serving proxy\registrar
Possess identical SIP and media behavior
Reside on the same Layer-3 network and are associated with the same SRD
Typically, the device is configured as the user agent's outbound proxy and the device is
configured (using the IP-to-IP Routing table) to route requests received from this IP Group
to the serving proxy and vice versa. Survivability can be achieved using the alternative
routing feature.
