New subject: [Kamailio-Users] SDP ending with CRLF and a=nortpproxy:yes

28 Sep 2008

I see: 	* [r4968] modules/nathelper/nathelper.c:
	  - fix the calculation of CRLF length when adding norttptoxy string
	  - patch by Alex Hermann (closes #2117700) 

And yes, it's that issue and therefore fixed in 1.4.1.

 a=nortpproxy:yes

 Hi!

 Same issue with 1.4.0. I'm migrating from 1.1.1 to 1.4.0, but 
 force_rtp_proxy() now adds a sdp line with a beginning 0x00, 
 so line looks like 
 0000   00 61 3d 6e 6f 72 74 70 70 72 6f 78 79 3a 79 65  
 .a=nortpproxy:ye
 0010   73                                               s
 But no \r\n\r\n in front anymore in 1.4.0.

 Someone to direct me to the propper source file,pls?

 Walter

 Hi Jerome,

  Hi All,

 Just FYI, I had to disable the nortpproxy test here because  it breaks
  thomson ST2030 endpoints : with that line, they
would just plain 
 ignore the messages containing the SDP ...  was i with malformed SDP (empty lines
inside SDP before the   a= line), 
  or just the presence of the a=nortpproxy:yes line
made the   ST2030 go 
  mad?

 Cheers,
 Daniel

 Cheers,
