Voice over IP Primer
Introduction
Voice over the Internet Protocol (VOIP) is one of the hottest topics for multi-location businesses of any
size because of its promise to transmit voice over data networks free of charge. Instead of paying the
phone company to route long distance calls between of ces, any IP data network can route the calls
over a private intranet or the public Internet and save thousands of dollars annually.
The ideal customer for this technology is a business with multiple locations. We’ve found that typically
25-40% of a company’s long distance bill is spent on intra-of ce communication. Recouping this portion
of the long distance bill can add up to signi cant savings.
Many companies have invested thousands of dollars in their voice and data networks. Multi-Tech’s
approach to Voice over IP is to protect that investment by tying both the voice and data network
together with our MultiVOIP gateway. MultiVOIP is a point-to-point, or point-to-multipoint, IP gateway.
It integrates seamlessly into the data network and operates alongside existing PBXs, or other phone
equipment, to simply extend voice capabilities to remote locations. The voice traf c essentially “rides
for free” on top of the data network, using the data infrastructure and hardware already in place.
With MultiVOIP, a small investment will pay for itself within the  rst six months to one year and then
start paying the company back. In our company example, which we will refer to throughout this primer,
we have three locations that utilize a MultiVOIP solution: Minneapolis-corporate, Los Angeles-branch
of ce and London-branch of ce. At headquarters, they have 60 employees and 16 phone lines. At the
Los Angeles of ce there are 12 employees and 5 phone lines. And, in London, there are 8 employees
and 4 phone lines. In the following ROI analysis, you can see that even with low long distance rates,
MultiVOIP will return the company’s investment within 4 months. Beyond that, the company will start
to pro t from the solution.
While VOIP is a compelling technology for a business to embrace, the challenge is in bringing together
the two very different worlds. This primer will serve to educate you on the voice network, the data
network and the new converged network utilizing our MultiVOIP gateway. In addition, it will cover many
of the frequently asked questions that a data communications manager and/or telecommunications
manager may have with the new technology. Finally, we will put it all together and discuss how to
con gure a MultiVOIP Voice over IP network.
