[Kamailio-Users] NAThelper and multipart SDP

[Pascal Maugeri]

Sure!

Here it is:

--pascal-boundary
Content-Type: application/sdp

v=0
o=- 3376939113 3376939113 IN IP4 10.1.1.248
s=pjmedia
c=IN IP4 10.1.1.248
t=0 0
a=X-nat:0
m=audio 4000 RTP/AVP 115
a=rtcp:4001 IN IP4 10.1.1.248
a=rtpmap:115 AMR/8000
a=fmtp:115 octet-align=1
a=ptime:20
a=maxptime:400
a=sendrecv
m=application 4001 udp TBCP
a=fmtp:TBCP queuing=0; tb_priority=1; timestamp=0; tb_granted=0;
poc_sess_priority=1; poc_lock=0

--pascal-boundary
Content-Type: application/resource-lists+xml

<?xml version="1.0" encoding="UTF-8"?>
<resource-lists xmlns="urn:ietf:params:xml:ns:resource-lists" xmlns:xsi="
http://www.w3.org/2001/XMLSchema-instance">
 <list>
  <entry uri="sip:blue at pascal.net <sip%3Ablue at pascal.net>" />
 </list>
</resource-lists>

--pascal-boundary--


I was checking the nathelper source code (nhelpr_func.c) and it looks that
only a content-type of application/sdp is accepted.

-pascal
