Re: Difference between digital phone and VOIP

["Sue" <sodom@xxxxxxxxxx>]

The way I understand it, and I could be wrong, is that Digital Telephony is
a broad term encompassing both VOIP and ISDN to mention a couple.  VOIP is
exactly what it says.  It converts voice to IP, Internet Protocol, for
routing over the Internet, thus avoiding tolls because it's traveling along
with the other network traffic.  I don't think the term Digital Telephony
implies anyone's particular wiring.  It is just a general term.

I think in any area where bandwidth is an issue, because phone packets are
traveling right along with all other Internet traffic, then packet loss may
occur.

I took this from a news article:

"Shaw Digital phone calls travel directly from Shaw's secure private network
to the tried-and-true public telephone system. They do not travel over the
Internet. The result is a more reliable and higher quality phone service."
