Voice Over IP is a telecommunication technology that has been around for many years.

Through its many years of development and the highly increased availability of broadband Internet, it has become as good as / or better than the good old telephone.

VOIP phones are plugged in to the Ethernet or network jack in your office wall and are powered from the central switch.
Your computer plugs to the back of the phone, so that one Ethernet/network wall jack is enough for one office/desk.

Voip telephony beats regular telecom costs by as much as up to 40%.

Monthly plans as low as $34.99
(pricing is volume based)

Features include:

VOIP can be integrated with Outlook and one can dial a phone number from the Outlook Contacts screen: just select the contact and click the dial button and your desk VOIP phone will call the number.

In addition to a desk phone, a softphone can be installed on a PC or laptop computer. This allows you to take your office phone number on the road and place as well as receive calls, retrieve voicemail etc. from your laptop.
