Hi all, I want to extract the channel ID from a line in SDP (a=channel:d87c363c1b5b4f13@speechrecog) I can extract this line, but I don't know how can I have only the ID (d87c363c1b5b4f13)
Do you have a way for me please ? thanks in advance SDP example: *********** m=application 1544 TCP/MRCPv2 1 a=setup:passive a=connection:new a=channel:d87c363c1b5b4f13@speechrecog a=cmid:1 m=audio 5002 RTP/AVP 8 101 ************* My conf: My result: "line in the SDP body is a=channel:d87c363c1b5b4f13@speechrecog" I want only: d87c363c1b5b4f13 in specific avp onreply_route[reply_mrcp] { xlog("L_INFO","$avp(startlog) In REPLY ROUTE MRCP - fu : $fu , si : $si , rs: $rs\n"); if(has_body_part("application/sdp")) { if (search_body("m=application.*TCP\/MRCPv2")) { if(search_body("a=channel:.*")) { $var(i) = 0; $var(whileflag) = 0; while ($var(i) < 10 && $var(whileflag) != 1) { $avp(aline) = $(rb{sdp.line,a,$var(i)}); if($avp(aline)=~"a=channel") { xlog("line in the SDP body is $avp(aline)\n"); $var(whileflag) = 1; } $var(i) = $var(i) + 1; } xlog("var i = $var(i)\n"); } } } }
