请解释我如何在那里获取呼叫 uuid。当我接通电话时。 https://www.plivo.com/docs/getting-started/web-sdk/make-outgoing-calls/
// Make outgoing calls
function call() {
if ($('#make_call').text() == "Call") {
// The destination phone number to connect the call to
var dest = $("#to").val();
if (isNotEmpty(dest)) {
$('#status_txt').text('Calling..');
// Connect the call
Plivo.conn.call(dest);
$('#make_call').text('End');
}
else{
$('#status_txt').text('Invalid Destination');
}
}
else if($('#make_call').text() == "End") {
$('#status_txt').text('Ending..');
// Hang up the call
Plivo.conn.hangup();
$('#make_call').text('Call');
$('#status_txt').text('Ready');
}
}
