Great, 
Basically my goal is to create a hig performance Auto-Dialer sort of thing in which I plan to fetch values from DB and push those values to kamailio using any module TMX or Dialog(as u mentioned) and as soon the intended destinaion answers Bridge the call to Media-Server to play an announcement..
This is sort of my personal experiment for this weekend.

Thanks,
Sammy.

Hello,

if you look to do something like click to dial (ringing user A first, when answering, then refer it to user B (or media server)), then maybe you just use dialog module with dlg_bridge command:

Hi, 
Thanks alot, I found the same stuff inside the kamailio-3.2/kamailio/examples/kamailio folder and now trying to implement some changes. Do you think It'll be difficult to originate call using this script and then later once call is Answered bridge it to a Media-Server to do its part !?

Thanks alot,
Regard,
Sammy.

Hello,

the headers have to be terminated in \r\n. In a shell script for click to dial, here is the used form:

cat > $FIFO <<EOF
:t_uac_dlg:$name
INVITE
$URI
.
.
"`printf "${FIXED_DLG}To: <$URI>\r\nCSeq: $CSEQ INVITE\r\nContent-Type: application/sdp\r\n"`
"
"`printf "v=0\r\no=click-to-dial 0 0 IN IP4 0.0.0.0\r\ns=session\r\nc=IN IP4 0.0.0.0\r\nb=CT:1000\r\nt=0 0\r\nm=audio 9 RTP/AVP 8 0\r\na=rtpmap:8 PCMA/8000\r\na=rtpmap:0 PCMU/8000\r\n"`

Hello list,

I'm using Kamailio 3.2 and am trying to send a SIP request from fifo to kamailio using below format.

#kamctl fifo t_uac_dlg MESSAGE sip:103@ mydomain.org  . . "From: 101@mydomain.org To: 103@mydomain.org Contact: mydomain.org Content-Type: text/plain; charset=UTF-8" "INVITE"

But I see this reply from Kamctl
