asterisk users - Jul 2004 - How to calculate the price for Asterisk based Solution

Hi,

We have potential client which would like to offer to him VoIP
solution for 2000 subscribers (SIP based Phones) and 2 x PRI ISDN
interfaces to the PSTN. In the next stage the subscribers will be
increased up to 13,000. Because I am not haven't done similar big
project I don't know how to calculate the price. The one way is using
number of subscribers and the other is using PSTN channels (60 in this
case). Also I have to calculate some price for consultants in case
that we have some problems. Also I have to calculate more hardware
servers for reservation, voice mail, billing, UPS and etc.

   Please give me some suggestions.
   Is there any regular price?

What your asking for is difficult for the following reasons:-

1.  What level of redundancy do you want in the system?

2.  What network load is already in place...is new network cable going to be
dedicated to this project?

3.  What network switches is the client currently using...are new switches going
to have to be from the same manufacturer to reduce management costs?

4.  What functionality is required from the phones...with voice only suffice or
would other services show a cost benefit analysis (CBA)?

5.  Are all users going to be located in one site or over multiple sites?

6.  What implementation timetable is being looked at?

These are what I can think in 20 seconds.  A project of this nature would
require a disciplined approach ensuring client 'buy in' to all elements
and clear communication internally within the client, by yourself, to ensure all
requirements from top management down to the individual users are identified and
evaluated on a CBA basis to ensure a clear project goal and good implementation.

More information would be useful to ensure people can offer the best advice.
