Gates Launches Microsoft VoIP Portfolio, Predicts Demise of PBX
(http://www.crn.com/networking/202403364 )
Office Communications server raises many important questions with
VOIP. The first question is whether or not softswitch (IE IP PBX) will
scale for large enterprises. Is the x86 Windows platform secure
enough. In order to scale either more processors are needed or
processor boards that can take the off load the voice processing. The
other factor is that larger enterprises will probably need to cluster
to avoid a single point of failure. The other unknown is if Windows is
secure enough. I just imagine someone hijacking a Windows box and
running up all all sorts of toll charges.
Then there is the issue of purchasing additional licenses when
Asterisk is available for free. Asterisk is a soft switch, but one can
run it on a embedded box. The other factor is that since Asterisk runs
on Linux you can run SE Linux and disable the unneeded functions.
The other challenge is softphone security.
In the end I think we see smaller MS shops as the primary market.
