if you take a look at the classic SIP trapezoid below, you will probably come 
to conclusion that their is nearly no way internet (excepted are very special 
network setups, e.g. private networks only) to make any QOS for the RTP 
packets, because you do not know which way they will take.

      Proxy -SIP- Proxy
     /               \
   SIP               SIP
   /                   \
