Network Routing Service

The Network Routing Service (NRS) application provides network-based routing, combining the following into a single application:

•H.323 Gatekeeper — The H.323 Gatekeeper provides central dialing plan management and routing for H.323-based endpoints and gateways.

•SIP Redirect Server — The SIP Redirect Server provides central dialing plan management and routing for SIP-based endpoints and gateways.

•NRS Database — The NRS Database stores the central dialing plan in XML format for both the SIP Redirect Server and the H.323 Gatekeeper. The SIP Redirect Server and H.323 Gatekeeper both access this common endpoint and gateway database.

•Network Connect Server (NCS) — The NCS is used only for Media Gateway 1000B (MG 1000B) and Virtual Office solutions.

•NRS Manager web interface — The NRS provides its own web interface to configure the SIP Redirect Server, the H.323 Gatekeeper, and the NCS.

The NRS application provides routing services to both H.323- and SIP-compliant devices. The H.323 Gatekeeper can be configured to support H.323 routing services, while the SIP Redirect Server can be configured to support SIP routing services. The H.323 Gatekeeper and the SIP Redirect Server can reside on the same Signaling Server.

Each system in an IP Peer network must register to the NRS. The NRS software identifies the IP addresses of systems based on the network-wide numbering plan. NRS registration eliminates the need for manual configuration of IP addresses and numbering plan information at every site.
