Ab
stract:
Although the internet w
as not designed to carry voice and other delay sensitive streaming m
edia, thecom
bination of: wide bandw
idth residential access, technical standards that facilitate low cost econom
ies ofscale, forbearance from
taxing and government regulation, and som
e unique features is driving the migration
of Voice O
ver IP (V
oIP) from
enterprise to consumer applications. A
lready the small startup pioneers are
facing competition from
brand name providers such as V
erizon and AT
&T
. Poised for entry into the V
oIPspace are all the cable T
V providers w
ho are now m
oving beyond beta rollouts into expanded geographicofferings.
While there are several variations on service features and a range of costs w
hat nearly all these VoIP
services share is a cost less than 1/2 of basic circuit switched services. In addition m
ost service providersprovide the full set of class services (e.g. call w
aiting, conference calling, caller ID, etc) and unlim
iteddom
estic local and long distance calling for the same low
flat rate.
By taking advantage of the intrinsic portability of the signaling schem
es used in Session Initiation P
rotocol(S
IP) these services typically go beyond "m
e-too" voice telephony and allow such expanded capabilities as
multiple off prem
ise extensions, unified messaging, presence, and m
ultimedia support beyond just voice. In
the early stages of development are hybrid com
binations of wide area w
ireless cellular telephony togetherw
ith local area wireless V
oIP.
This presentation w
ill review the recent history and current state of the art in V
oIP as applied to residential
public network telecom
munications services. A
n overview of the key foundation technologies w
ill beprovided along w
ith a look at the likely future evolution of the technology and services.
