From: <[EMAIL PROTECTED]> I have doubt on the SIP messagee body, consider the message has SDP and ISUP payloads, iam constructing the sip packet using Structures in C, I referd the document RFC 3204, i have doubt on following fields...
1.content length : is it tells the lenght of SDP ? Content-Length (if present) is the length of the entire body. In your case, the body is a MIME-multipart, which contains both the SDP and ISUP, along with the MIME-multipart overhead. 2.content type : The entire body will have type multipart/alternative. Within the multipart type, the types of each body part is given. The SDP will be application/sdp. 3.unique boundary : how we will know the boundaries of SDP and ISUP or other payloads if present? The multipart separator is specified in the 'boundary' parameter of the multipart/alternative type. See section 7.2 of RFC 1341 for all the details.
