About the SRX Series Integrated Convergence Services Features and Functions

This topic gives a high-level view of Integrated Convergence Services components and features. Integrated Convergence Services optimizes and secures VoIP communication and applications running on Juniper Networks SRX Series Services Gateways. It integrates hardware and software on the SRX210 and SRX240 devices to provide the following main features and functions:

• A standards-based Session Initiation Protocol (SIP) media gateway (SRX Series MGW) that connects VoIP networks to the PSTN so that calls can be made from and routed to local analog telephones, fax machines, and SIP IP phones configured for the SRX Series MGW.
• A SIP survivable call server (SRX Series SCS) that provides local call handling and basic call routing when the SIP peer call server cannot be reached.
• Emergency call support that allows the SRX Series MGW to intercept all branch calls whose called number matches that of a configured emergency number, for example 9-1-1. The SRX Series MGW routes these calls out to a local PSTN trunk or to the peer call server.
• Lifeline support to connect analog phone that is connected to FXS port to FXO1 port (PSTN) in the event of power failure.

Integrated Convergence Services supports the Open Convergence Architecture and gives you the flexibility to select the SIP call servers, IP phones, and service providers to be used.
