Eight important factors to consider when getting VOIP
VoIP, or Voice over Internet Protocol, is becoming the
alternative to the high cost of local telephone service. The
primary advantage is the savings on local and long-distance
calls. There are also savings for all the extra features that
are included in the basic VoIP service. Traditional telephone
companies charge extra for things like call display, voice mail
and call forwarding. Many VOIP providers offer these features at
little or no cost.
With this new technology there are eight important factors to
consider before you take the plunge and get a VOIP service.
1) You need a High Speed Internet Connection
In order to use VoIP, you need to have a high-speed Internet
connection, such as DSL or cable. If you do not have this then
your costs to have VOIP will be higher.
2) Power Outages
VoIP is dependant on commercial AC power from your local
utility. Your standard telephone runs on phantom power that is
provided over the line from the telephone central office. Even
if your AC power goes out, your standard telephone still works.
The VOIP gateway, ATA equipment and high-speed Internet modem
requires AC power. During a power failure if you do not have a
UPS or back up power system, you will not be able to make or
receive telephone calls. This could be a problem if you need to
call 911. These is why some people use Voice over IP for long
distance calling only and keep their existing telephone number
with their standard telephone service.
3) Emergency 911
The 911 systems do not know what you physical address is because
of the SIP addressing scheme. With SIP there is no way to
associate a geographic location with an IP address, so calling
911 in an emergency can be a serious problem. You could be in
Vancouver using a Toronto number and the 911 dispatchers would
not know that. Most VOIP service providers have a work around
that has you call into their 911 center where they can find out
where you are and then dispatch the local emergency services to
you. This could cause a delay in getting emergency services to
you quickly. The standard telephone service uses a North
American Number Plan and the local service provider knows your
address based on the number called that's in their
database.
Keep this in mind when deciding to cancel your standard
telephone service. Ask your provider how they are handling 911
emergency calls; your life may depend on it.
4) You may still need your standard telephone line
Satellite TV subscription services and home security systems all
use a standard phone line to communicate. There is currently no
way to integrate these products with VoIP. Consider your
requirements if you are planning to discontinue your local
standard telephone service.
5) Local Telephone White Page Listings
VoIP providers may or may not offer directory assistance or
local white page listings.
6) Reliability
Because VoIP uses a high-speed Internet connection, it is
susceptible to all the problems normally associated with home
broadband services. All of these factors will affect call
quality: Latency, Jitter, noise, and Packet loss. Telephone
conversations can become distorted, garbled or lost because of
these transmission errors. It is important to have a High
Quality connection from a reputable internet service provider.
7) Security
Like many Internet based programs, VoIP is susceptible to worms,
viruses and hacking. Make sure you use anti-virus and firewall
security software.
8) Extensions
The standard telephone service is analog. It uses 2 wires to
transmit and receive the telephone call. You local telephone
company may have already outfitted your residence with extension
jacks throughout the house. With VOIP, the main connection point
becomes where your High Speed Internet modem is located. You may
not have cabling connections at that location to the rest of the
house. The solution is to have an electrician assist you in
cabling the extensions or using a cordless telephone.
