SR 2330/4134, CS 1000 components

The following diagram shows the main components of Secure Router 2330/4134 and Communication Server 1000.

SR has two modules SIP Gateway (SIP GW) and SIP Survivability Module (SSM) that together interworks with CS 1000 to provide SIP survivable gateway functionality at the branch. SSM is a software-only subsystem on the Secure Router through which SIP calls are routed to the CS 1000. This module includes SIP B2BUA based proxy and SIP Registrar. SIP GW is software and hardware subsystem on the Secure Router that provides PSTN connectivity. The User Agents (UA) are SIP endpoints.

For detailed information about SSM operation please refer to Secure Router Release 10.2 guide NN47263-510 Configuration — SIP Survivability.

For detailed information on SIP GW please refer to Secure Router Release 10.2 guide NN47263-508 Configuration — SIP Media Gateway.

The main CS 1000 components are Call Server (CS), SIP Signaling Gateway (SSG), SIP Line Gateway (SLG), SIP Proxy Server (SPS) and Network Routing Service (NRS). SSG handles SIP trunking and SLG takes care of SIP endpoints or SIP Lines.
