Thanks for the suggestion. This isn't the problem because the "2000"
extension was only setup for the purpose of documenting the problem for
email. The "real world" setup involves only valid 20 digit callerids.
I also don't think the toll-free system relies on caller id otherwise it
would be trivial to spoof (not that it would save you any money since
the call is free anyhow).
