Today's focus: Premises convergence - an update

By Steve Taylor and Larry Hettick

Continuing our retrospective on convergence, today we'd like to
look back at how our original vision of premises convergence and
has evolved since our first look at the subject five years ago.

When we originally defined premises convergence, we were
impressed by PC software that allowed PC-to-PC "phone calls."
And we're happy to report that now the original issues with VoIP
call quality have largely been solved with proper engineering
deployment and with acceptance of QoS-friendly protocols like
MPLS.

What we didn't anticipate in 2000 was the wide-scale acceptance
and deployment of IP phones that use Ethernet connections, nor
did we foresee how quickly the desktop phone would turn into a
computing device. Nor did we expect that unified messaging and
unified communications would be packaged into IP telephony
systems so quickly. But there's no doubt now - the IP phone is
bound to replace traditional phone sets in the enterprise, and
unified communications is now seen as an integral part of the IP
telephony business case to improve person-to-person
communications.

Perhaps the biggest change in premises convergence was about how
the premises themselves would converge - or, more accurately,
how IP telephony makes the premises boundaries of legacy telecom
systems disappear. With IP telephony, the user's geographic
location no longer dictates user access to communications
features. One of the benefits of IP telephony is that when a
user has access to a broadband IP network connection and an IP
phone or softphone, the user can enjoy the same "on-premise"
telephony features offered by more traditional direct
connections to a legacy PBX or single central office.

So today, we'd like to add these dimensions to our original
category of premises convergence and reserve the right to add to
the list in another five years.

Next time, we'll look at how access convergence has evolved.
