Business class VoIP works in much the same way as for residential VoIP with one major difference. With business class VoIP a T1 is usually delivered to your office that provides both VoIP voice lines and Internet service. This means that your VoIP provider and your ISP are the same company. This distinction is very important once you need more then 3 or 4 lines. Since your Internet connection is coming from the VoIP phone company problems such as latency, jitter, and static are greatly reduced.
Basically, your call has to travel a shorter distance. With residential, your call goes from Verizon DSL or Comcast Cable, to Vonage, to the person your calling. That’s 3 steps or hops and problems can occur anywhere along with way. With business class VoIP, the 1st 2 hops are the same provider so things work better and you can get more calls on the same Internet connection.
Business class VoIP also has the advantage of being dynamically allocated. This means that when fewer people are on the phones, the Internet speed is faster. Voice always gets priority, so phone lines are always available. Packages are available from 5 to 105 lines or more and may come with unlimited calling or a large allotment of included minutes.
Business service is far more important then residential, so it is necessary to choose the right carrier. There are several major carriers like Verizon and Sprint and many smaller national carriers. There are even more regional carriers that only service a small area and even more resellers that just package someone else’s service. Let the experts at KeenSystems help you navigate through the maze of carriers and offers.
This is the 2nd major use of VoIP. You can “connect” to your office phone system from anywhere there is a high speed internet connection. Using a special VoIP telephone or a Laptop “soft phone” you can work from home or a hotel and it is just like being in your office. You have access to all your phone system features including the intercom, paging, all outside lines, voice mail, and even your extension can ring on your VoIP phone. Best of all, you do not lose the use of your computer. One high speed internet connection can run your VoIP phone and your PC at the same time.
With this same technology, you can link multiple offices together into one seamless phone system. You can even share lines or the one voice mail system. You can even run your entire phone system over your office LAN or WAN without separate voice wiring (often called Pure IP or IP Based telephone systems), though that is very expensive and complicated and is best suited for very large companies with full time IT staffs.
