New subject: sdp extra \r\n in multipart body

22 Aug 2017

Hi Daniel! Thanks for your reply.

The rtpengine module I think it's expecting two \r\n like:

...pcma/8000\r\n
\r\n
--uniqueboundary
....
cpc,9\r\n
\r\n
--uniqueboundary--

I saw the code and I modified it but Can any one cofirm if multipart has to
be like

...pcma/8000\r\n
\r\n
--uniqueboundary

Or
...pcma/8000\r\n
--uniqueboundary

Or any one of those?

Thanks again!

Diego

  Hello,

 there is \r\n after

 a=rtpmap:8 PCMA/8000

 because

 --uniqueBoundary--

 is on next line.

 Maybe is the fault of the code extracting sdp from multi-part body. Open
 an issue on github bug tracker not to forget about it. If nobody looks at
 it, I will try to do it, but it may take few days given traveling.

 Cheers,
 Daniel

 Hi guys,

 I have the following multipart body

 Content-Type: multipart/mixed;boundary=uniqueBoundary
 Remote-Party-ID: <tel:1112222;phone-context=+54>
 <1112222;phone-context=+54>
 Content-Length:   364

 --uniqueBoundary
 Content-Type: application/sdp

 v=0
 o=user1 53655765 2353687637 IN IP4 111.111.111.111
 s=-
 c=IN IP4 111.111.111.111
 t=0 0
 m=audio 6000 RTP/AVP 8
 *a=rtpmap:8 PCMA/8000*
 *--uniqueBoundary--*
 Content-Type: application/gtd
 Content-Disposition: signal;handling=optional

 IAM,
 CPC,20
 GCI,885sdfasdf1123

 --uniqueBoundary--

 As you can see *--uniqueBoundary *before *a=rtpmap:8 PCMA/8000* has not
 an extra '\r\n'. Is this correct? Or should have it?

 The thing is that rtpengine is receiving sdp with no final '\r'n' from
 kamailio:

 Dump for 'offer' from 127.0.0.1:37388: { "sdp":
"v=0#015#012o=user1
 53655765 2353687637 IN IP4 111.111.111.111#015#012s=-#015#012c=IN IP4
 111.111.111.111#015#012t=0 0#015#012m=audio 6000 RTP/AVP 8#015#012*a=rtpmap:8
 PCMA/8000"*, "ICE": "remove", "direction": [
"pub", "priv" ], "replace":
 [ "origin", "session-connection" ], "transport-protocol":
"RTP/AVP",
 "call-id": &quot;1-17755(a)111.111.111.111&quot;.111", "received-from": [
"IP4",
 "111.111.111.111" ], "from-tag": "1", "command":
"offer" }

 And the resulting sdp from rtpengine is this:

 --uniqueBoundary
 Content-Type: application/sdp

 v=0
 o=user1 53655765 2353687637 IN IP4 172.16.213.16
 s=-
 c=IN IP4 172.16.213.16
 t=0 0
 m=audio 35066 RTP/AVP 8
 *a=rtpmap:8 PCMA/8000a=sendrecv*
 a=rtcp:35067

 The problem is related with that '\r\n' but Is this a malformed message or
 a possible bug?

 Thanks in advance!

 Diego
