[OpenSIPS-Users] [Open-sips]: Problem in message body of Notify

[Shefali Dutta]

Hi,
   Open-sips is send Notify with MIME message body which seems to be incorrect as per RFC.

According to RFC 2046:

"The boundary delimiter MUST occur at the beginning of a line, i.e.,

   following a CRLF, and the initial CRLF is considered to be attached

   to the boundary delimiter line rather than part of the preceding

   part.  The boundary may be followed by zero or more characters of

   linear whitespace. It is then terminated by either another CRLF and

   the header fields for the next part, or by two CRLFs, in which case

   there are no header fields for the next part.  If no Content-Type

   field is present it is assumed to be "message/rfc822" in a

   "multipart/digest" and "text/plain" otherwise."



Open-sips is sending an extra CRLF after the boundary between different message bodies as a result, MIME headers are also assumed to be part of the body by the parser.

Here is the message dump of Notify:
