Hmm, it looks like the number is used for directory assistance [0] in North America at least.
>Throughout North America, 1-XXX-555-1212 will connect to directory assistance for the specified XXX area code
I wasn't able to find a link between that number and TellMe/MS. They appear to have had the 1-800-555-TELL (8355) [1] number but no mention of the 1212 number.
Though a google for the number +"Microsoft" reveals they appear to use that number in a couple of their SQL server books [2]
