Might you be able to reach a 976 number with 950-1022 to get into MCI
or by dialling "10222#" and then dialing the 976 number in another
area code?

I guess that IBT can't be expected to block these since they never
hear the tones.

[Moderator's Note: IBT doesn't hear the tones, but MCI sure does!
Calls via 10222 or 950-1022 here to an anywhere-976 number return an
intercept saying 'at the present time, MCI does not connect with 976
numbers.' Sprint is the same way.  PAT]
