Chapter 3 - Before You Deploy

If your organization has special rate plans, those should be incorporated into the least-cost routing tables.

Network Topology

You will need the network topology information described in LAN/WAN Considerations on page 52 when you design your dial plan and configure PathNavigator to manage your video network.

If the network is physically changed, you will need to update PathNavigator’s network information so that it can manage the video network effectively.

PathNavigator provides the means for you to assign ISDN numbers to endpoints. The way numbers are assigned depends on your network:

❑E.164 provisioning — Choose E.164 provisioning if you are using private numbers.

❑ISDN alias assignment — If you assign ISDN numbers to endpoints, then the ISDN ranges need to be provided to the gatekeeper. These numbers must be coordinated with your local ISDN provider as these numbers cannot be self-populated. Assigning numbers that are not in your domain will result in failed calls when users outside the organization try to access users within the organization with self-populated numbers.

❑Automatically assigned numbers — PathNavigator can automatically assign direct inward dial (DID) numbers or gateway extensions. You cannot automatically assign both types of numbers on the same network.

Neighbor gatekeepers

Neighbor gatekeepers allow for the distribution of the workload across logical boundaries within the organization. This enables more efficient use of the network by limiting communication across WAN links. When a call originates in one gatekeeper’s zone and that gatekeeper is unable to resolve the dialed address, it will be forwarded to the neighbor gatekeepers for resolution.
