High-definition voice is gaining traction in the communications industry. IT managers should know that high-definition voice maintains compatibility with existing systems, so the transition to it is quite straightforward. But, as seamless as the transition may be, Knowledge Center contributor Jeffrey Rodman explains that there are ways to smooth the transition process further. Here he offers some of the most important points IT managers should consider when deploying high-definition voice.
all IT managers: I have some good news for you if you're thinking about
deploying High-Definition Voice in your organization. The move from
standard narrowband audio to HD is much easier than the original shift
from POTS (plain old telephone service) to VOIP to (voice over IP).
Why? Because HD Voice (also known as Wideband Audio Telephony) uses
existing standard VOIP signaling, protocols and networks to carry its
enhanced audio bandwidth. So, in many ways, once you've made the move
to VOIP, you've already done most of the legwork in deploying HD Voice.
HD Voice makes talking on the phone far more productive and much
more pleasant than what you're used to because it restores the
two-thirds of the audio spectrum that conventional phones take out. HD
Voice makes talking on the phone sound as if you're in the same room as
the person on the other end. If you haven't experienced HD Voice
yourself, think of High-definition Television (HDTV) or High Definition
Radio (HD Radio). Once you've heard and seen the difference, you
realize exactly what you were missing. As a result, HD Voice is gaining
traction in the communications industry.
The good news for IT managers is that HD Voice maintains
compatibility with your existing systems, so the transition is quite
straightforward. In fact, it's relatively simple because the protocol
is still standard Session Initiation Protocol (SIP). Even better, the
data rates are generally comparable to standard G.711
This is a little-known fact-many IT managers incorrectly assume that
bandwidth requirements are higher but they are not, so take note!
But, as seamless as the transition may be, there are always ways to
smooth the transition process further. So let's take a look at some of
the most important points to consider, starting with some hardware
