Hi Avi, The pertinent lines are : <action application="set" data="group_confirm_key=exec"/> <action application="set" data="group_confirm_file=/usr/local/freeswitch/scripts/confirm.js"/> So I'm a step further now, I get: 2012-01-16 15:26:20.954602 [ERR] confirm.js:61 near  SyntaxError: invalid returnreturn true; The same occurs if I use brackets around the "true". I've adapted the script slightly to use a pin pulled from a database (but I'm no Javascript Guru, so I'm guessing I missed a glaring bug !). Thanks for your help. ============================================================= // confirm.js - Freeswitch Call PIN Check // // console_log("info", "Destination: "+ session.destination + "\n"); // if(!session.getVariable('my_legconf')) {   console_log("info", "No B-Leg Confirmation Requested \n");   exit(); } // // // Variables... // var v_continue = false; var conf_pin = session.getVariable('my_legpin'); var attempts = 3; var sound_file = "ivr-please_enter_pin_followed_by_pound.wav"; var pin_lastdigit=""; var pin = new Object(); pin.digits = ""; function parseInput (session,type,data,arg) { if ( type == "dtmf" ) { pin_lastdigit = data.digit; pin.digits += pin_lastdigit; console.log("info","Read digit " + pin_lastdigit + "\n"); return false; } } // // if (session.ready()) { session.answer(); session.flushDigits(); console.log("info","Starting PIN Collection\n"); var cnt = attempts; while (session.ready() && ! v_continue && cnt-- > 0) { session.execute("sleep","200"); session.streamFile(sound_file,parseInput); while (pin_lastdigit != "#" && sesson.ready()) { session.collectInput(parseInput,pin,5000); } console.log("info","Collected PIN: " + pin.digits + "\n"); if ( pin.digits == conf_pin ) { v_continue = true; console.log("info","PIN OK !.\n"); } else { pin_lastdigit = ""; pin.digits = ""; session.flushDigits(); } } } else { console.log("info","Session not ready.\n"); } // // if(v_continue) { return true; } else { return false; } =============================================================
