CHAPTER 1 Introduction
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.
