You don't need a call routing platform: you need call routing data. As much fun as it is to build new systems, that might not be your need.

I was tasked to design a system that would give each end user a unique DID from a pool of about 1,000 DIDs total. Every inbound call to a DID would then be forward to the end-users actual phone number (office, mobile, etc..).
WIth that in mind, to me it looks like a big waste of DIDs, and I could use custom extensions instead, with a single DID for everyone. Each end-user is assigned a 5 digit code (an extension pretty much) and gets re-routed accordingly. I believe using Asterisk and/or FreePBX I could still collected all the data that is needed.
The two-stage process will give you different results from having DIDs. Calling into an IVR/Auto Attendant and entering an extension is going to be considered old school for a lot of folks. In the US, almost everybody has a DID listed on their business card or advertisement. Otherwise you're signaling that you'd like to keep the caller at a distance; "I'm not going to let you ring my phone directly; I'm going to send you through a gauntlet of call transfers". PSTN DIDs aren't a scarce resource unless you require them all to have 212 area codes (for example of a big city).
Estimated inbound minutes is 500,000 a month, so that requires another 500,000 outbound minutes because each call is forwarded. One million minutes a month does turn out to be expensive, close to U$8,000/month from some quotes that I have gotten.
Rather than building it yourself, you could use somebody else's platform -- if they'll give you access to the billing data and give you the call-forwarding options you need. -- PhonePower offers business-oriented service with unlimited minutes -- Phonebooth <http://phonebooth.com/> (a Bandwidth.com <http://bandwidth.com/> company) has unlimited minutes I'd recommend you contact these guys directly and explain your need. They all have technical people on this list. --- mark at ecg.co +1-229-316-0013 http://ecg.co/lindsey
