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

[Schober Walter]

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?
