1. The device determines the SIP Interface on which the incoming SIP dialog is received
and thus, determines its associated SRD.
2. The device classifies the dialog to an IP Group (origin of dialog), using a specific
Classification rule that is associated with the dialog's SRD and that matches the
incoming characteristics of the incoming dialog defined for the rule.
3. IP Profile and inbound manipulation can be applied to incoming dialog.
4. The device routes the dialog to an IP Group (destination), using the IP-to-IP Routing
table. The destination SRD (and thus, SIP Interface and Media Realm) is the one
assigned to the IP Group. Outbound manipulation can be applied to the outgoing
dialog.
