Hi All,
I had a question on the usage of INVITE.
Is the offer answer model to be followed only when
the body is described using SDP??
i.e. if I have INVITE with no body and the 200 OK
response also has no body, then is this a valid SIP
sequence? Since I am conveying all the information
in SIP headers like Subject etc. I don't need to use a
body and I am wondering if this will violate the offer-answer
model defined in RFC 3261.
INVITE (no body)
-------------------------------->
200 OK (no body)
<--------------------------------
ACK (no body)
------------------------------->
Appreciate your response,
Vijaya
