Not only is the above not a valid extensions.conf line, the poster even 
put Ttr in the sample.  Horrible.

Assuming NANPA dialing, try

exten => _8NXXNXXXXXX,1,Dial(IAX2/user at provider/${EXTEN:1})

See the notes in my .sig about the "r" option to dial.

r: Generate a ringing tone for the calling party, passing no audio from
the called channel(s) until one answers. Use with care and don't insert
this by default into all your dial statements as you are killing call
progress information for the user. Really, you almost certainly do not
want to use this. Asterisk will generate ring tones automatically where
it is appropriate to do so. "r" makes it go the next step and
additionally generate ring tones where it is probably not appropriate to
do so.
