I've been in touch with people at CDW, where we buy some of our
enterprise-grade stuff (when we do buy such things). They don't seem to
offer the Cisco 79x0 phones, but their "telephony expert" suggested the
Polycom 501/601 phones, as units that are reasonably easy to use and
work well with Asterisk. Does anyone have comments to make in favor or
against the Polycom models?

Brian,
Asterisk is definitely enterprise ready but you have identified some of
the weak points below. Still, if you have a fairly static phone config
and just need basic phone apps, then Asterisk is easily do-able for the
average office.
Paging is best done using an analog speaker system - which looks to
Asterisk like a simple Analog phone line. Other than that, you can use
the intercom feature available with Cisco 7940 or 7960 phones and just
setup a "conferencing" group that uses the intercom feature on all your
phones. It won't work perfectly, but it will work.
If you think you need 24 lines then a PRI is the way to go. You'll get
CallerID and the cost is much cheaper for the setup and maintenance.
If you go with POE switches, that will be more expensive than buying
power bricks for each phone, but you will get some nice honking Cisco
switching power that will vlan out your Voice traffic from your Data.
The cheaper solution is to get a Cisco 2924 XL-EN (that "EN" part is
*very* important) and bunch of power bricks. It cost would be about half
of that of going with a Cisco 3524-PWR
The advantages of VoIP are tremendous, and installation is about half
the cost of a traditional service, but... it still ain't cheap.
If you guys want an interrum solution (hosted VoIP), then look us up. We
would be happy to help you take you guys off your old PBX and move you
over to the world of VoIP. And if you need any Asterisk help, let me know.
BTW: I've gotten several Kick-butt Asterisk servers from Cerient (Jason
Tower). The costs have all been around $2k (plus the Digium hardware),
and they would work great as and Enterprise Asterisk server for an
office of your size or larger.

Hi Y'all,
Coming back around to the Asterisk topic again.. Now that we're
looking at the possibility of expanding off-site operations, having
a
completely-VoIP office telephony solution is seeming more and more
prudent. So I'm looking for some advice from folks who have
deployed
whole-office systems using Asterisk (as well as input from folks
that
have used non-Open-Source software). I've already thought of the
following points:
- Need a real butt-kicking server to handle as many as 24 inbound
lines
(using a Digium TDM2400), plus however many inter-office calls may
be
occurring (plus room for expansion). Right now I'm contemplating a
Core
2 Extreme-based system.
- In the absence of intelligent managed switchgear, need separate
switchgear for 100bT for the phones. Possibly with PoE.
- Need to have all the features of our existing PBX. General
call-handling features are a cinch with * dialplan and
applications, but
I'm finding, in particular, the "page" or "intercom" feature seems
to be
more of a challenge in the VoIP world. Paging ability is essential.
- Phones need to be simple enough that our folks can use them, but
complex enough to handle things like paging. I've seen
recommendations
for the Cisco 7960 set. Price is a consideration, as our initial
investment will be 30 phones.
I'm also all-ears for other options. It'd be fantastic in $boss's
eyes,
I'm sure, if we didn't have to abandon the investment we've already
made
in our current Nortel MICS system. Unfortunately, so far the only
way
I've found to interface the PBX with an Asterisk system is via
analog
adapters. Icky, because of course then you lose a lot of the PBX
features for the Asterisk users.
Also, if there's anyone that would like to come visit our facility,
evaluate our current system and our needs and make a quote, I'd be
very
happy to entertain it.
Thanks a lot!
Cheers,
~Brian
