Embedded Gatekeeper System Example
The present example shows a voip system with three gateways, one of whose
embedded gatekeeper functionality directs voip traffic in the system. The
system design will give 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.
The gatekeeper equipped MultiVOIP is an analog model (MVP410G) whose
four channels are all connected (via FXO interface) to a PBX at a company’s
factory site in “Compton.” The second gateway is a T1 digital voip gateway
(MVP2410) connected to a PBX at the company’s headquarters in
“Mucksville.” The third 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).
To implement this configuration, we start with the gatekeeper-equipped
MultiVOIP at the Compton site.
1. MVP410G. For the MVP410G at Compton, we need first to configure its
phonebook with the gatekeeper configuration in mind. (We’ll presume that its
technical configuration has already been completed. Its IP address would have
been set in the
Configuration | IP Parameters screen and its four channels
would have been
set to “FXO” in its
Configuration | Interface screen. )
