Can we include letters as part of the recognition of phone numbers?

It would be great if we could include letters as recognizable as part of the phone number pattern. I know that android.util.Patterns.PHONE doesn't cover this, but it should be easy enough to come up with a custom pattern to allow letters, at least in the non area code part of the phone number.

Start by locating the phone-number recognition entry point and its use of android.util.Patterns.PHONE. Confirm the intended format for letters in the non-area-code portion, then add or update coverage so those numbers are recognized without changing area-code handling.
