Owner of the  Dog and Pony Studio in Vegas, and audio-pro John McClain shot me a link the other day while he was trying to find something ELSE I’d written about.  We DID eventually find what he was looking for (see: https://courvo.com/2011/02/isdn-down.html), but it doesn’t matter, as his link was pretty handy, too.

Users of ISDN will find this especially handy:   ACCESS CODES FOR ATT, MCI, SPRINT LONG DISTANCE CARRIERS.

Thanks, John!
