Internet-based telephony –
Voice-over-IP – (VoIP) has
been around for years but has not
reached the mainstream market.
The reasons for this are quite
clear to those of us who have
tried VoIP software:
Products which have a true
cost-saving advantage over
standard telephones do not have
comparable quality.
Call-completion rates are very
low due to firewalls and the use
of Network Address Translation
(which renders over 50% of
residential computers unable to
communicate with traditional VoIP
software).
The User Interface is typically
bloated and requires substantial
configuration and technical
skills.
When you are using PSTN line, you
typically pay for time used to a
PSTN line manager company: more
time you stay at phone and more
you'll pay. In addition you
couldn't talk with other that one
person at a time.
In opposite with VoIP mechanism
you can talk all the time with
every person you want (the needed
is that other person is also
connected to Internet at the same
time), as far as you want (money
independent) and, in addition,
you can talk with many people at
the same time.
If you're still not persuaded you
can consider that, at the same
time, you can exchange data with
people are you talking with,
sending images, graphs and
videos. last comment : February 2018
