this is what i wrote to the original poster:
the place you want is the function check_user_full().
I did something similar recently (you find it in trunk, i am attaching
the relevant code below) to match
users from the 'Username' field in the auth field.
For your goals, you should modify (or replicate) the block
below, and do a get_header(req, "To") and a bit of parsing to
extract the string you want. At this point, you should be
able to match the request against the entry in the users list
(your entry [441612412070] is both a user and a peer, but
the match-by-name is on the users list first)
hope this helps
