[Asterisk-Users] A rather big setup.

[Vedran Dakic]

Hello,

Those people currently aren't using any kind of phones, but the investment
company that has this building "in the works" wants to deliver everything
for them so they just have to - move in and do business. 

What worries me is the fact that when you have 100-200 offices - they're
used to having 2-3 lines only for them - one for fax, two for voice, etc.
So, in a way, having in mind around 200-300 outbound calls at peak time is
pretty much "normal". Also, when you think of the number of phones - it
would only be normal to assume for people to have up to 1000 internal phone
conversations peak (the less transcoding - the better, of course).

I have a freedom of making whatever I want, so I can have a separate LAN for
VoIP purposes only - a bunch of dedicated patch panels, VLANs on Cisco
switches, or whatever. I'm just considering this setup way before it has to
go online because of the price of traditional PBX for this kind of setup
which can only make you hurl. And you know how much potential upgrades cost
for a setup like this - a traditional PBX can be a nightmare :(

Cheers,
Vedran.

I think there is more to consider.
One or two fat machines in the basement forr connecting to the PSTN is
very fine.
But are all the people allready using voip handsets, or old fashioned
analoge handsets? If so, you need quite a large number of channelbanks.
You speak of 300/1500 concurrent phone calls? If so how many handsets
are you considering?
Is the lan capable of handling this load?
Is the lan 100% dedicated for voip, or are there a bunch of
servers/workstations also using this lan?

Interesting project....
