Hi! I'm new user to freeswitch.I write a c program to dial and play a wav file. I want to know hangup-cause.But it does not work.The Event-Name i got is "SOCKET_DATA" not "CHANNEL_HANGUP". Can you help me to fix it and get hangup-cause?

Then i will dial lot of number but only on work time (9:00-11:00,14:00-17:00).So I want to use crontab to send custom event to crotrol dial start or stop.So how to send and receive custom event ?
Beside the crotab and custom event,any other better idea to control when to start or stop ?

Thanks!

int main(void)
{
    esl_handle_t handle = {{0}};

    esl_status_t status1,status2,status3;
    int done = 0;
    esl_status_t status;
    time_t exp = 0;

    //esl_global_set_default_logger(7);
    status1 = esl_connect(&handle, "localhost", 8021, NULL, "ClueCon");

    esl_events(&handle, ESL_EVENT_TYPE_PLAIN, "CHANNEL_ANSWER CHANNEL_ORIGINATE CHANNEL_HANGUP");

    status2 = esl_send_recv(&handle, "api originate user/1001 &playback(/tmp/a.wav)\n\n");

    if (handle.last_sr_event && handle.last_sr_event->body) {
        printf("Sucess --- %s\n", handle.last_sr_event->body);
    } else {
        // this is unlikely to happen with api or bgapi (which is hardcoded above) but prefix but may be true for other commands
        printf("Fail --- %s\n", handle.last_sr_reply);
    }

    while((status = esl_recv_event(&handle, 1,NULL)) != ESL_FAIL)
    {
                if (status == ESL_SUCCESS)
        {

        }
