Resource Priority Namespace Network Domain setup

Resource Priority Namespace Network Domain setup

This chapter provides information to add, update, or delete Resource Priority Namespace Network Domains

For additional information, see topics related to multilevel precedence and preemption in the Cisco Unified Communications Manager Features and Services Guide.

About Resource Priority Namespace Network Domain setup

In Cisco Unified Communications Manager Administration, use the System > MLPP > Namespace > Resource Priority Namespace Network Domain menu path to configure Resource Priority Namespace Network Domains.

Cisco Unified Communications Manager uses Resource Priority Namespace Network Domains to support Voice over Secured IP (VoSIP) networks by using Multilevel Precedence and Preemption (MLPP) for Session Initiation Protocol (SIP) trunks.

MLPP, with configured Resource Priority domains, prioritizes SIP–signaled resources and enables indications related to precedence and preempted calls. End users can establish secure calls when the calls traverse SIP trunks.

There are five registered namespaces for resource priority:

  1. dsn—Defense Switched Network
  2. drsn—Defense Red Switched Network
  3. q735—Commercial equivalent of the DSN
  4. ets—Emergency Telephone Service
  5. wps—Wireless Priority Service

Note


Cisco Unified Communications Manager accepts “Q735” and “q735” as the same value. It transmits “q735’ when signaling an MLPP call on the SIP trunk.


Resource Priority Namespace Network Domain deletion

You cannot delete a Resource Priority Namespace Network Domain that any device is using. To find out which devices are using the Resource Priority Namespace Network Domain, from the Resource Priority Namespace Network Domain Configuration window, choose Dependency Records from the Related Links drop-down list box and click Go. If the dependency records are not enabled for the system, the dependency records summary window displays a message. For more information about dependency records.

If you try to delete an Resource Priority Namespace Network Domain that is in use, Cisco Unified Communications Manager displays an error message. Before deleting a Resource Priority Namespace Network Domain that is currently in use, you must perform either or both of the following tasks:

  • Assign a different Resource Priority Namespace Network Domain to any devices that are using the Resource Priority Namespace Network Domain that you want to delete.
  • Delete the devices that are using the Resource Priority Namespace Network Domain that you want to delete.

Resource Priority Namespace Network Domain settings

The following table describes the Resource Priority Namespace Network Domain settings.
