asterisk users - Apr 2006 - Suggestion Request: Coloc Provider in Chicago, IL area

Hello all!

I always prefer to get referrals from fellow professionals, and this is such a
request. I'm looking for the following:

1. Colocation providers in the chicago area to store a small server for the
purpose of setting up a VOIP service (including pstn connection via Digium
cards) for between 100-10,000 users. Obviously value is a big part, but
reliability and network speed are also factors, as well as whether or not
they'd
let the client have T1/T3 lines for his PSTN connects.

2. PSTN<->SIP OR PSTN<->IAX providers that client can optionally use
instead of
Digium T# interface cards. (Network proximity to Chicago area a MUST, obviously)


I thank all of you in advance, your experience and feelings towards people
you've dealt with in the past are far more insightful than reading company
websites.

Cheers all!
