Hi Alex, I am adding my own SDP body to the reply and set the content-length to 350 already. The extra content-length: 0 is causing it to be malformed.
Question: Is there a way to generate SIP reply with SDP payload from config file. I saw there is uac_send_req but no support for reply so far...Please suggest. I want to send this message from Kamailio: SIP/2.0 200 OK Via: SIP/2.0/UDP 10.0.0.5:52653;rport=52653;branch=z9hG4bKPj60f74c5d68574dc5ae3cbfdd21ba5f12;received=10.11.200.48 From: "cust1" <sip:[email protected]>;tag=0cba06eab62d47d1ace9c8834bbe0396 To: <sip:[email protected]>;tag=02eb90a2953b26682001111237ca6e13-e339 Call-ID: 7d383971684b44f792cfe84043bf8b5a CSeq: 15351 INVITE Content-Type: application/sdp Content-Length: 350 v=0 o=- 3688213899 3688213900 IN IP4 10.99.52.17 s=Blink 1.4.2 (Windows) t=0 0 m=message 2855 TCP/MSRP * c=IN IP4 10.99.52.17 a=path:msrps://10.99.52.17:2855/12673656159856;tcp a=accept-types:message/cpim text/* image/* application/im-iscomposing+xml a=accept-wrapped-types:text/* image/* application/im-iscomposing+xml a=setup:active -----Original Message----- From: sr-users [mailto:[email protected]] On Behalf Of Alex Balashov Sent: Tuesday, April 25, 2017 7:24 AM To: Kamailio (SER) - Users Mailing List <[email protected]> Subject: Re: [SR-Users] How to eliminate Content-Length:0 from sl_send_reply Hello, What leads you to the conclusion that the Content-Length: 0 header is "extra", and in need of a "workaround"? -- Alex On Tue, Apr 25, 2017 at 12:21:32PM +0000, Pranathi Venkatayogi wrote: > Hi, > How do I eliminate Content-Length:0 from sip reply when using sl_send_reply? > I wanted to generate 200 ok, with SDP payload.
