Got a bit of info via email (gotta remember to not bother asking the
boss as he won't give up anything).
When looking at a VoIP PBX you need to consider a number of things.
For example what kind of network do you have, do you already have a
clean cat5e or better PoE network or do you need to upgrade / install
equipment or wiring. What kind of hand offs will you be using SIP,
POTS, T1, etc.? Do you currently have latency problems? What kind of
telephony integration are your costumes after? What kind of services
will your PBX need to offer? etc. etc. etc.
Given that we are turning a massive amount of open space into new areas
(converting a class 10,000 cleanroom to a class 10,000 greyspace, a
class 100 cleanroom, offices and other storage) which means new walls
and cables pulled, I can request what I want (doesn't mean they'll do it).
I'd prefer something more than POTS so that we don't have a lot of lines
running from the curb to the building. Last job I had where I did the
phones (6+ years ago) used a T1 to each site with an Avaya PBX system. I
don't mind if the internal network does VOIP, but I don't have good
experience with them in terms of quality (thick accents are made almost
unintelligible to myself and others in the lab) over network connections.
As for Asterisks the PBX box can be fairly low grade, a decent desktop
quality box will do. You'll need a card for your hand off and that is
about it. I would recommend using Cisco phones but that is me, others
on this list have way more Asterisks experience.
I've looked at some of the info provided on some sites (like
http://www.rhinoequipment.com/). I see that there are PCI cards for
driving the external lines, but I'm not sure how the system would be
linked over to the cables inside the building. The old Avaya system had
a board that was wired out to a patch panel for punching down twisted
pair connections (which were carried out through the building in CAT5e
wiring).
Personally I went with a proprietary product (ShoreTel) for my voip
install but we had something like 40 phone and 50 users. For the
smaller office (6 people) we used a hosted solution.
Ah, I miss the days when I had an office ;)
In any case it is a fun project so keep us informed as information
rolls your way :)

I'm trying to spec out a PBX or similar system for a startup company. The
requirements for such a system would be 10-15 phones (either analog or
digital phones), 1 or 2 fax lines (obviously analog) and voicemail for same,
as well as the recommended link to the outside world. Mostly I'm trying to
figure out about how much this would cost with setup as part of a
presentation. Unfortunately I can't give out a whole lot of information as I
haven't been able to get any of my questions answered (this was dumped on me
today and wanted by Wed. morning along with servers, switches, Internet
access, etc...).
Not looking for sales pitches, but wouldn't object to responses from local
vendors, heheh.
