Mobile HD voice request of the day–TAC code database mapped to HD voice/AMR-WB support?

Is there a TAC code database that maps HD voice support (AMR-WB support) to each TAC (i.e., to each mobile device)?

This should be a fairly simple piece of work and useful to have for carriers that wish to do a pre-deployment survey of handset devices to determined what handsets (customers) already are able for supporting HD voice.
