Dipankar,
 
   A dialog/Session is not established unless a 2xx response is sent back by
the UAS [Gateway]. Hence no media is sent out before 183 session in
progress.
 
Thanks,
John

Subject: [Sip] Query on Early Media ( 183 Session in Progress ) 

Hi All,

    This is query regarding Early Media ( 183 Session in Progress ) .

Can an  Implementation ( Gateway ) send Media before sending out the 183
Session in Progress over UDP Transport in response to a INVITE   ? Is there
any RFC/draft on the details of 183 Session in progress and Media handling ?

Thanks in advance .

Best Regards,
