The NRS application provides routing services to H.323 devices and
SIP-compliant devices. The H.323 Gatekeeper can be configured to
support H.323 routing services, while the SIP Redirect Server NRS can be
configured to support SIP routing services. The H.323 Gatekeeper and the
SIP Redirect Server NRS 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.
When configuring the NRS it is necessary to enable the NCS. Ensure that
the check box "Network Connection Server enabled" is checked in the NRS
configuration window of CS 1000 Element Manager.
For information about configuring the NRS, see IP Peer Networking
Installation and Commissioning (NN43001-313).
