Overview

A Profile Agent plug-in handles registration requests from many clients. The SIP Profile Agent is a framework which allows different SIP service providers specific registration behaviours such as 3GPP, IP Multimedia Subsystem (IMS), IETF, and Proprietary.

The SIP profile defines the configuration of the service provider. Some provider type specific registration behaviours are implemented as ECOM plug-ins and are used to register the profiles of the corresponding type.

The SIP Profile Agent subsystem stores the SIP profiles in a persistent storage. These profiles contain information necessary to provide the required registration behaviour. The SIP profile stores the following main parameters:

• The user-friendly name of the service provider

• The type of profile, for example 3GPP IMS, Proprietary, and IETF

• The AORs of the user

• The Internet Access Provider Identifier (IAP ID) used

• The address of the SIP registrar server and the SIP proxy server with optional connection and security parameters

• The compression and security preferences

• An indication of whether the profile is always automatically registered, or only when it is used by the SIP application

• Any number of extension parameters stored as key-value pairs
