Hi
I got the following error when dealing with SIP INVITE with multi-part when
the client is behind NAT:
May 12 15:27:04 test /usr/sbin/kamailio[1792]: ERROR: nathelper
[nathelper.c:2954]: can't extract body from the message
The SIP INVITE message looks like:
INVITE sip:t...@test.net <sip%3at...@test.net> SIP/2.0
[...]
Content-Type: multipart/mixed;boundary=gnkr
Content-Length: 659
--gnkr
Content-Type: application/sdp
Content-Length: 330
v=0
o=pascal 1273565967736 1273565967737 IN IP4 10.1.1.226
[...]
It looks the Content-length within the multi-part is not accepted.
I fixed it changing the source code of parser/sdp/sdp_helpr_funcs.c,
in get_sdp_hdr_field() function:
switch(hdr->type){
case HDR_CONTENTTYPE_T:
case HDR_CONTENTDISPOSITION_T:
case HDR_CONTENTLENGTH_T:
replaced with:
switch(hdr->type){
case HDR_CONTENTTYPE_T:
case HDR_CONTENTDISPOSITION_T:
(I'm using kamailio 3.0.1)
Cheers
Pascal
