blockout

I'm trying to use the BLOCK OUT - I need to block 10 digit and 11 digit calling - but allow 3 digit calling to exts.
I've set (..........) 10 digit.
I've set (...........) 11 digit.

So if user calls 18005551212 < 11 digits blocked
or if user calls 8005551212 < 10 digit blocked

but if the user calls the 3 digit ext it's blocked.

I tried to hard-code one button calling, but the block out blocked the preprogrammed option.
