THE IP WAY TO HEAR FROM THERE
WHY IP AND BROADCAST PHONES MAKE THE PERFECT PAIR
TELEPHONY: it’s the technology for electronic transmission
of voice, fax, or other information between distant parties.
Indeed, broadcasters are all about connecting remote sounds,
ideas, and voices with our audiences. Telephony is elemental
to broadcasters.
We receive or gather - TV folks say “ingest” - audio programming
from satellites, telephone callers, remote talent via codecs,
and downloaded audio iles. We assemble this audio and
mix with local content - talent, commercials, trafic, weather -
then we broadcast the resulting program audio to our listeners.
Keeping with the telephony theme, it’s becoming clear that
IP telephony is displacing the traditional connections with
which we grew up. And broadcasters using IP telephony in
its many forms are noticing something - it frequently sounds
better than the POTS or ISDN service it’s replacing. This improved
audio quality is possible, and now even practical, along
several key paths in a broadcaster’s operation. Even better, IP
Telephone calls carried in whole or in part by IP sound better
than those carried by traditional transports - all other
things being equal. Improvements come by dint of better quality
phone instruments, “4-wire” connections from end to end,
endpoints negotiating best codec usage, and even from intelligent
and powerful audio processing in an IP phone system
designed for on-air use.
HERE ARE SOME REAL-WORLD EXAMPLES OF IMPROVED
AUDIO QUALITY USING IP TELEPHONY:

rector reports that all phone calls – even from traditional phones
– are sounding clearer and are easily intelligible. Audio levels are
brilliantly consistent, too, even from reporters and newsmakers
calling in from the other side of the globe.
» At radio stations where a Telos VX IP phone system is installed,
radio talkshow hosts, DJs, and call screeners are telling me their
callers sound noticeably better - clearer - and with less of that
“cell phone distortion”. Show hosts spend less time asking a
caller to “repeat that, please” and more time in real conversation.
Caller audio levels are consistent, too. Board ops hardly touch the
phone fader, as the call-to-call level is dependable.
