Grey Headline (continued) Introduction TANDBERG VIDEO COMMUNICATIONS SERVER ADMINISTRATOR GUIDE Call Processing Diagram One of the functions of the VCS is to route calls to their appropriate destination, based on the address or alias received from a locally registered endpoint or neighbor zone. There are a number of steps involved in determining the destination of a call, and some of these steps can involve transforming the alias or redirecting the call to other aliases.
Grey Headline (continued) Dialing by Address Types TANDBERG VIDEO COMMUNICATIONS SERVER ADMINISTRATOR GUIDE About the Different Address Types Dialing by H.323 ID or E.164 alias The destination address that is entered via the caller’s endpoint can take a number of different formats, and this will affect the specific process that the VCS follows when attempting to locate the destination endpoint. The address types supported by the VCS are: • IP address e.g. 10.44.10.1 or 3ffe:80ee:3706::10:35 • H.
Grey Headline (continued) Hop Counts TANDBERG VIDEO COMMUNICATIONS SERVER ADMINISTRATOR GUIDE About Hop Counts Configuring Hop Counts Each search request is assigned a hop count value by the system that initiates the search. Every time the request is forwarded to another neighbor gatekeeper or proxy, the hop count value is decreased by a value of 1. When the hop count reaches 0, the request will not be forwarded on any further.
Grey Headline (continued) Administrator Policy TANDBERG VIDEO COMMUNICATIONS SERVER ADMINISTRATOR GUIDE About Administrator Policy Administrator Policy and Authentication The VCS allows you to set up a set of rules to control which calls are allowed, which calls are rejected, and which calls are to be redirected to a different destination. These rules are known as Administrator Policy. Administrator Policy uses the source and destination of a call to determine the action to be taken.
