Converting phone LETTERS into DIGITS in T-SQL / MS SQL Server

0

How to convert letters used in phone numbers into digits, i.e. input string '1-800-FLOWERS' should return '1-800-3569377', using a T-SQL? In Oracle, I would have used PL/SQL TRANSLATE function, however I need to do it in T-SQL and there is no similar function in T-SQL.

Please take a look at this image - this is the transformation I am looking for Thanks!
