[VoIP] Traditional PBX or VoIP Based?

[Dennis D Hock]

I would have to agree with John and maybe try looking at a Legend or NEC
depending upon how big you need to be.

Asterisk is a wonderful application and does alot but I would'nt want to
hang my calls on it for a business serivce and certainly not to my local
police and fire services.  TDM may be going away but it is far from dead
yet and it offers a very mature and stable envirnoment upon which to build.

I have to agree with Mark

Asterisk for business, hospitals and emergency services, even the more
mundane office type requirements is NOT a safe solution
The so called "legacy" telephone systems are a much better solution, are
much more reliable than any general purpose PC based solution, and, when
ones time is factored in, cheaper.
The 842 and 942 phones are OK for my desk, but I would NEVER sell then
to a customer. No backlit display, mediocre sound quality and no power
over Ethernet are all killers, IMO.

Depending on requirements, a nice NEC system or systems, available
through either Graybar or Target Distributing will give many years of
reliable service at a really low cost. Voice mail in skin is available
as well, that makes the Asterisk VM truly "Comedian Mail"

Asterisk is fine for us to play with and connect or switches together,
but if you put one in a real business, you had better be ready to
babysit the system, the users, and do LOTS of customizing.
Also, better crank up the limits on your business liability policy!
