Hi Dude,
this seems like an incall., anyways, lets assume that the media is played from other side: & it should play only after we send 200 OK for prack.
183 is kind of "hello tunes", when we get 183+SDP - so when 200ok prack comes it gets played..
if its not clear , please let me know.
& 183 followed by 180 ringing, thats all Ok. No such rule.

<------200 ok for PRACK---

Mu doubt comes over here can a party B send a 183 before 180 ..... I mean the 1xx response has to maintain in some sequence ?
