event_route[xhttp:request] { if ($hu =~ "hangupCall"){ $var(body) = $rb; xhttp_reply("200", "OK", "",""); jansson_get_field($var(body), "callid", "$var(callid)"); jansson_get_field($var(body), "cseq", "$var(cseq)"); if (t_cancel_callid("$var(callid)", "$var(cseq)", "22")) { xlog("L_NOTICE", "t_cancel_callid============"); } exit; } xhttp_reply("404", "Not Found", "",""); exit; } According to this route, the answered call cannot be hung up。How should I hang up the answered call in xhttp routing, similar to freeswitch's uuid_kill。
