[USR-TC] Disable v.90 based on DNIS

Does anyone have the steps to set it up so I can have a incoming connection to my HiperDSPs be limited to v.34 based on DNIS? I'd like to set up an alternate number so that customers with problems connecting at v.90 would have that disabled when they use that number. Thanks.
