Good morning all, I will be using both digital (which knows when the other part answers) and analogue (when, at least in Italy, doesn't!) I need to calculate the total duration of an outgoing call. Calls also must have a preset max duration. I need to schedule a warning message (1 min before timeout) and a hangup (on timeout) for BOTH digital and analogue lines. This is the core of the code, reduced to the bone: var allowedSecs = 300; // max length 5 min . session.answer(); var sessOut = new Session("sofia/gateway/realtoneFXO/" + dialedNum + "@192.168.0.216:5060"); if (trunkIsDigital) { sessOut.execute("set", "execute_on_answer_1=sched_hangup " + allowedSects + " alloted_timeout") sessOut.execute("set", "execute_on_answer_2=sched_broadcast + " + (allowedSects-10) + " playback::" + soundDir + "one_min_left.wav both"); } else { // will schedule message and hangup on allowedSecs + graceTime to be calculated according to destintation (time to ring/answer) } if (sessOut.ready()) { bridge(session, sessOut); } sessOut.hangup(); session.hangup(); /*** HOW LONG DID THE CALL (bridge) ACTUALLY LAST?? .. for billing purposes **/ Thanks and Happy Easter!
