The power of competition is amazing. I have been using Vonage for a few
years, and can not tell the difference between Vonage and BellSouth
except for the lower price and substantially more features offered by
Vonage.

Today, I got an offer in the mail from AT&T offering VOIP and similar
features at the same price as Vonage. As long as Vonage continues to
provides excellent service, I will not change, but it is nice to see the
market place working.

VOIP is a diaster waiting to happen and when it does, all you VOIP
losers...er...users are going to be stuck with no way to communicate.

You heard it here first.

What, I can't hear you, can you speak a little louder.- Hide quoted text -

Now Reggie, you must know that VOIP can't possibly compete with
ancient 2 copper wire and switchhouse technology where every
connection you make degrades the signal!
Or can it??

Legacy telephony solutions are narrowband, which seriously limits the
achievable
quality. Wideband codecs could potentially be used in digital
telephone systems, but this
has never been practical enough to gain any real interest.
In fact, in traditional telephony applications, the speech bandwidth
is restricted much
more than the inherent limitations of narrowband coding. Typical
telephony is band
limited to 300 Hz to 3400 Hz. This bandwidth limitation explains why
we are used to
expect telephony speech to sound weak, unnatural, and lack crispness.

Telephony band speech.
Most phone lines connected to a household are traditional two-wire
copper cables. Pure
digital connections are typically only found in enterprise
environments. Due to poor
connections or old wires, significant distortion is often generated in
the analog part of the
phone connection, a type of distortion that is entirely absent from
VoIP implementations.
The cordless phones so popular today also generate significant amounts
of analog
distortion due to radio interference and other implementation issues.
