Pros
One advantage of using VoIP is the cost of the service. Phone
service using VoIP costs less than similar service offered from
traditional phone services, especially in regards to long
distance telephone calls. Long distance calls through VoIP are
offered at flat rates, which will ultimately benefit the
consumer. Also, VoIP allows the consumer to share its voice and
data equipment, which means that the costs are also shared. In
other words, if you have an Internet connection already in
place, VoIP can be used at almost no extra cost, and any network
capacity that you are not currently using can be used for making
calls.
Another key benefit of using VoIP is the fact that incoming
calls can be automatically routed to your VoIP phone regardless
of where you are connected to the Internet. This is especially
important for those who go on business trips.
VoIP phones can also be integrated with other Internet services,
such as videoconferences and file transfers. A user can send or
receive messages or data while on their VoIP phone.
Cons
One cause for concern with VoIP is emergency 911 service. Before
the government stepped in, 911 was not an optional feature for
VoIP service providers, and 911 calls made after-hours were not
guaranteed to be routed to the local area's emergency call
centers of the caller. However, the U.S. government required
that all VoIP service providers make 911 service standard and
functional by September 2005. Some VoIP service providers have
appealed this deadline, so it would be wise for consumers to be
sure of what their service provider's policy on 911 is.
Another disadvantage of the VoIP service is the lack of
encryption, which means that it is relatively easy for someone
to eavesdrop on a VoIP call and even change the content of the
call. There are a few solutions to this problem, but they do not
guarantee full security of any calls. Airtight security would
require the user to utilize encryption and cryptographic
authentication, which are not yet readily available to consumers.
A third drawback is the inconsistent sound quality of the calls
made with VoIP. The sound quality is oftentimes fickle and calls
often have delays and echoes as well. This means that some calls
made with VoIP might not be as smooth and natural as calls made
over landline phones.
