Voip Network Example - Multitech MultiVOIP MVP100GK Gatekeeper User Manual

VOIP Network Example

The present example shows a voip network with three gateways, and a Gatekeeper directing voip traffic. The
network design gives phone users at each office toll-free access to both the company employee phones (most are
on PBXs) at the remote sites as well as the local PSTNs surrounding the remote sites. To implement this network
you should configure the voip gateways at the three sites and then configure the Gatekeeper.
The top gateway is a T1 digital voip gateway (MVP2410) connected to a PBX at the company's headquarters in
"Mucksville." Also, at the company's headquarters is a Gatekeeper with a separate IP connection to the IP
network for directing the voip traffic. The Gatekeeper should be configured after the voip gateways are
configured. The second gateway, located in one of the company's small sales offices in "Rootersville," is a first-
generation MultiTech gateway with two analog channels (MVP200), one serving an analog phone (via FXS
interface) and the other giving access to its local area PSTN (via FXO interface). The third gateway is an analog
model (MVP410) whose four channels are all connected (via FXO interface) to a PBX at a company's factory site
in "Compton."
To implement this network, lets start with the MultiVOIP gateway at the company's headquarters.
1. . For the MVP2410 at the company headquarters in Mucksville, we need to first configure its
MVP2410
phonebook with the Gatekeeper in mind. We will presume here that technical configuration is already
complete so that the MVP2410's IP address and other technical configuration parameters have already
been duly set.
