Here are some items that need to be kept in mind:
Support 800 phones (400 of which are analog)
Concurrent calls ... ? but need to guess high so that the server can handle this.
Voicemail will be required along with sending voice mail attachments to email server.
Flash panel for switchboard operator.
Needs to be a distributed server design for redundancy and fail-over.
Will need to be integrated into an existing PBX until each building is switched over to use the Asterisk servers.
If calling 911 from a building among multiple buildings, how can EMS find that person based upon the call?
What type of data line should be used in this setup? T1?
The physical network will support QOS and the like, so that is not an issue.
What type of design/setup do you recommend for this? How about server resources...ie...CPU, RAM, Disk space.
How about backups? Does imaging work best if a server were to fail?
Any thing else you can think of?

If this is a project for your work and it's your first Asterisk
deployment then definitely don't go the big bang approach in the way
you've outlined. If you do you could well be out of that job in 6
months!
The first thing I'd recommend you do is find 10 or 20 people who are
suitable as early adopters. The set up a single Asterisk server and
give the early adopters a SIP phone each thats in addition to their
normal desk phone and ask them to see how they go using the SIP phones
for calls to each other, external calls and whatever else would make
sense. Then 6 months and a lot of learning/experience/frustration
later you'll know whether to get answers to your original questions or
not.

Greyman. |

Ditto.....
If you need to quantify the consultant to the powers that be just ask
for an "Infrastructure Audit". I have done several in the past that
have saved tons of money that encouraged further phone projects.
Finding dead phone lines to discovering unused but rented telcom gear
is always fun. Also when setting up you test group make sure they
actually use the phone and often...

I would have to agree with Grey Man, a pilot project is one way to start
up.
I would also seriously recommend buying some consulting time from an
experienced Asterisk PBX vendor/dealer/consultant.
The cost is negligible in light of the scope of your project.
A pilot project will only give you a glimpse of what is required.
You have to have a design that incorporates your eventual build out.
A pilot by itself is not going to give you that. You will need help from
a source that can bring their experience to help you tip toe around the
potential land mines you can encounter.

The items most people do not address are:
- QA - How do You tell if you you having Jitter,Packet Loss etc BEFORE
the user scream
- Disaster Recovery - from the small - DNS smokes - To Larger - * box
with 96 ports smokes
- Insuring EACH and EVERY piece ox network SUPPORT and USES QoS
-Vendor SLA - How do YOU measure the service, WHAT happens outside 9-5
-HW Support - Your Quad port DIGIUM card smokes. Can you live w/out it ?
Should you have a spare on hand ?
If so how many
-What TOOLS are you going to use to MONITOR this whole thing - all
servers, switches
-800 Phones - Minimum ..... Could be painful if folks are used to
traditional TELCO reliability and Quality
