problem

its kind of silly but I can see some kind of rationale for it if you
are trying to allow both the signalling and the media to see dtmf for
sure but you certainly need to ignore one of them.  Technically, INFO
dtmf does not exist, the draft expired and was not adopted so it's a
rogue method now.  Everyone already uses it so i'm sure it will stay
around.  I don't think there is a real way to negotiate it however.
