Hi,

Has anyone implemented the 183 response handling? Did go through
draft-ietf-sip-183-00.txt  & draft-ietf-sip-call-flows-05.txt. One speaks
about inclusion of SDP in 183 response & sending of PRACK . While the other
says there is no need for SDP message in 183 response & hence no need for
PRACK.  Is there any other RFC which gives a clear idea about 183 response.

Let me know which of the two is correct & also, if there is no need for a
SDP body then how will the calling party come to know about the codec used?
>From RTP header?

Thanks in advance.

Regards,
Jitha
