Multi-Tech Systems MVP-3010 Optional Gatekeeper Functions, Zone Management, Call Authorization

Embedded Gatekeeper MultiVOIP User Guide

Zone Management

Note. Zone Management and neighboring gatekeeper functionality are not included in the current software release. The discussion of this paragraph pertains primarily to the general theory of gatekeeper functionality. These functions are included in plans for subsequent software releases.

The gatekeeper allows or disallows call traffic between neighboring zones, depending upon established permissions. The zones themselves might be defined geographically (a company may have facilities in different cities, each being a separate network zone), by physical network connections (a range of IP addresses may comprise a zone, as may a subnet on a particular floor of a building), or by an organizational criterion (e.g., a large company might define separate network zones for engineering, manufacturing, marketing, and administration).

Optional Gatekeeper Functions

The MultiVOIP Gatekeeper supports the four main optional gatekeeper functions: call control signaling, call authorization, bandwidth management, and call management.

Call Control Signaling

The gatekeeper can, in “routed” mode, act as an intermediary for H.225 call- control signals between two endpoints participating in a call. In “direct” mode, this function is turned off and the endpoints exchange H.225 call-control messages directly.

Call Authorization

The gatekeeper can be programmed to restrict access (admission and registration) according to criteria set by the user.

Bandwidth Management

This is essentially dynamic bandwidth control (see “Bandwidth Control” section above).
