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.
Element Manager
Element Manager is a simple and user-friendly web-based interface that
supports a broad range of system management tasks, including:
• configuration and maintenance of IP Peer and IP telephony features
• configuration and maintenance of traditional routes and trunks
• configuration and maintenance of numbering plans
• configuration of Call Server data blocks (such as configuration data,
customer data, Common Equipment data, D-channels)
• maintenance commands, system status inquiries, backup and restore
functions
• software download, patch download, patch activation
