This chapter describes how the Cisco Voice Routing Center (VRC) works when integrated with Packet Telephony Center (PTC).
This chapter contains the following topics:
The VRC provides a tool for network administrators to manage the network dial plan for H.323-based VoIP networks. VRC provides a graphical user interface (GUI) for the initial and ongoing configuration of dial plans in Cisco VoIP networks (gateways, gatekeeper).
Before you can configure a dial plan, you must set up trunks and their signaling and create the associated gateways. To ensure a reliable VoIP network, you must also add the individual element configuration, including RADIUS, SNMP, and access lists. This configuration can be done manually or, more conveniently, through PTC.
VRC is a strategic and key network management tool for any service provider who wants to deploy an H.323 network.
The Cisco Packet Telephony Center (PTC) is a management solution for large-scale H.323 networks. PTC manages the network through Element Management Systems (EMS) or through the Cisco IE2100.
PTC provides overall configuration management of the network. When integrated with PTC, VRC becomes a module within PTC that provides management functions for H.323 dial plans.
When you use VRC integrated with PTC:
For more information on Cisco PTC, refer to the following documents on the Cisco website:
If you are using VRC as a standalone application, see "Cisco VRC Installation."
If you are using VRC integrated with PTC, we recommend that you perform the integrated PTC/VRC installation as documented in the PTC installation guide. This procedure installs PTC first and then installs VRC. Refer to the Cisco Packet Telephony Center Installation and Configuration Guide for more information.
Cisco Packet Telephony Center documentation is available at the following URL:
When VRC is installed as an integrated application with PTC:
To access VRC from PTC, click the Voice Routing Center button from the PTC launch pad (Figure 10-1).
The PTC launch pad, located at the top of the PTC Topology Manager window, displays the following buttons:
You can perform the following VRC operations from the PTC Launch Pad window:
|Note When integrated with PTC, the VRC GUI will not have a Topology View.|
If you are using VRC integrated with PTC, use the PTC Topology Manager instead of the VRC Topology View to add regions to the topology database.
When you add a region using the PTC Topology Manager, the following tasks are performed:
Use one of the following methods to add the new region to your dial plan in VRC:
If you are using VRC integrated with PTC, use the PTC Topology Manager instead of the VRC Topology View to delete regions from the topology database. When you delete a region, the following tasks are performed:
If you are using VRC integrated with PTC, use the PTC Topology GUI instead of the VRC Topology View. When you add network elements to the topology database, the following tasks are performed:
You can add the following network elements to the topology database using the PTC Topology Manager:
|Note Use the Design View in VRC to add the network element to your dial plan.|
To delete network elements from the topology database, use the PTC Topology Manager instead of the VRC Topology View. PTC will only allow you to delete the element if the element is not participating in a dial plan. When you delete network elements, the following tasks are performed:
If you are using VRC integrated with PTC, you must use PTC to add managed resources to the gateway.
If you are using VRC as a standalone application, see Gateway Attributes.
A gateway managed resource can be a:
When you add a managed resource to a gateway, the following tasks are performed:
To include the managed resource in your dial plan, manually reactivate the gateway.
If you are using VRC:
A gateway managed resource can be:
When you delete a gateway managed resource, the following tasks are performed:
When you are finished, manually reactivate the gateway.
When you use VRC integrated with PTC, the PTC Topology Manager maintains the element configuration information.
Element configuration information includes:
When you make changes to element configurations, the following tasks are performed:
|Note Whenever you make a configuration change to an element outside of the VRC, you must reactivate that element to ensure that the dial plan configuration is correct.|
When you are using VRC integrated with PTC, only gateways are marked for reactivation. VRC must learn about gatekeepers and directory gatekeeper element changes through other organizational-specific procedures.
For more information, see the "Reactivating an Element" section.
When dial plan changes are committed, VRC sends any dial plan changes that need to be reflected in the Topology View to PTC, for example, adding a gateway to a zone.
For more information on committing dial plan changes to VRC, see Committing a Dial Plan Design.
User authentication is the verification of the credentials of a user. User authorization determines the user's privileges and provides access control to the managed resources.
User privileges define the scope of managed resources for which a user has the right to perform a set of operations.
VRC, when integrated with PTC, uses CNS security services for the following user administration and authorization operations:
