Or maybe they'll respond the way that my local telco, The Monon 
Telephone Company, did: "Yes, we could certainly enable that feature for 
you, since it is a trivial feature on our switch.  But our tariffs don't 
require us to do that for residential customers, so we won't do it for 
you.  End of discussion.  Thank you for calling."

The only consolation is the knowledge that soon there will be no need 
for them, and it's almost certain they don't see it coming.
