This is the most common use of VoIP. It is also called VoIP lines or trunks. If
you have a high speed internet connection, like cable modem, DSL, or T1, you can
use your high speed connection to make phone calls on the internet. There are
many companies like Vonage, Lingo, and VoiceWing (Verizon) that offer VoIP
lines. Cable companies also offer VoIP lines, but only if you have their cable
modem service. So, to boil it down, instead of getting your dial tone from
Verizon over the traditional phone network, you get your dial done from your
internet company. Any phone system made (even an old one) can take advantage of
VoIP lines. You do not need an IP based (IP PBX) or even IP compatible phone
system. This is one of the biggest misconcetions about VoIP.
The
advantage of VoIP lines are:
Lower Bills. Usually you pay a flat monthly rate
and all your calls in the USA and Canada are free You can take your number with
you. If you move around the corner or across the country with VoIP you can keep
your existing phone number even if you move to a different area
code.
Multiple area codes. You can get phone numbers from different area
codes or even overseas numbers.
Portability. You can move the VoIP router
with you and take your service easily with you. You can even set it up to use
your laptop with a virtual soft-phone and a WiFi connections to make calls from
anywhere you can get high speed internet access.
Features. VoIP lines
come with Caller ID, Call Forwarding, and lots of other great features. The
problems with VoIP lines are:
Quality is not as good as traditional phone
service, but it's close and getting better all the time. Set up can be very
challenging, especially if you are planning on using your own
router.
Depending on how fast your internet connection is, it may be
possible to make several calls at the same time over the internet. However, the
more calls you make at once the slower your internet connection will be and the
poorer the sound quality of your calls will be.
Faxes, modem, and alarm
systems don't work well over VoIP lines. Sometimes they won't work at all. If
you need a lot of lines, you may need more then one high speed connection, so
the cost of the high speed internet connection may outweigh the
savings.
There are some minor technical issue using VoIP lines and
Automated Attendants and Voice Mail systems. If your internet access goes down,
all your phone lines go down too.
VoIP lines normally don't work if the power
does out, but you can set up back up batteries.
Right now the Government does
not tax VoIP service. If that changes VoIP may not be price effective anymore.
Making Calls Over the Internet--Business
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's vital that you choose
the right carrier. There are several major carriers like Verizon and Sprint and
many smaller national carrier that you've probably never heard of. 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 Teleco

Connection Remote Workers or Remote Offices....Voice over IP
Stations.
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's 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
don't lose the use of your computer. 1 high speed internet connection can run
your VoIP phone and your PC at the same time.
With this same technology,
you can link multiple office 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.
Voice over IP is very exciting and more and more people are
using it everyday. Let the experts at Teleco http://www.teleco4.com help you
understand if VoIP is right for you. Voice over IP is available on both the NEC
IPK and Toshiba CTX digital telephone systems.
