scope:

The specification of the SIP UNI in this document is based on a standard SIP User Agent (UA) connected to a Service Provider Network composed of standard SIP components (SIP proxies, etc.). Depending on the service scenario, the SIP UA can interact directly with an Application Server, or with another SIP UA via a SIP Application Server. The SIP UA implements standard SIP session control mechanisms for initiating sessions, and for responding to invites from another SIP UA or Application Server. Services are implemented in the SIP UA, in the Application Server (with the SIP UA interacting with the Application Server through standard SIP mechanisms) or in a combination of the SIP UA and Application Server.

This specification applies to a SIP UA associated with an individual SIP device as well as to a SIP UA associated with a SIP PBX. From the perspective of this specification, a SIP UA connects to a service provider network either directly, or via a SIP PBX .
