In your sample you're actually queuing "sleep(1000)" to the channel. 
So first it will queue play_and_get_digits, inside that loop it will 
find more commands in the queue, and exeute them, so in the end it 
will only execute a bunch of "sleep(1000)".
You're better of using a sleep in your module directly (not tell FS 
to sleep). Also you will need to poll the events in the loop 
somehow., checkout the perl sample here:

Peter,
I've changed to the below (adapted that Perl example) and I only hear 
the prompt for digits when the webserver times out after 60 seconds. 
Any time I make any call to ESL after the execute, I don't hear the 
prompt in a timely fashion. This is so complicated as I'm not really 
that good at software development, I'm more a systems/networks guy. I 
feel like a total thickie here, but the docs don't seem to explain in 
which order I should call things and expect to get replies, etc.
$esl = new ESLconnection('localhost','8021','ClueCon');
$event = $esl->events('plain', 'ALL');
//$event = $esl->filter("Unique-ID",$uuid);
sleep (1);
$res = $esl->execute("play_and_get_digits","4 11 1 5000 # 
ivr/ivr-please_enter_the_phone_number.wav 
ivr/ivr-that_was_an_invalid_entry.wav target_num \d+", "$uuid");
$job_uuid = $res->getHeader("Job-UUID");
$status = $res->getHeader("Reply-Text");
//$foo = $uuid . ' target_num';
echo $status;
$stay_connected = 1;
while ( $stay_connected ) {
    $e = $esl->recvEventTimed(0);
    if ( $e ) {
        $ev_name = $e->getHeader("Event-Name");
        # Should we check for the $job_uuid to match the background job ?
        //if ( $ev_name == 'BACKGROUND_JOB' ) {
        //    if ( $e->getHeader("Job-UUID") == $uuid ) {
        //        $call_result = $e->getBody();
        //        echo "Result of call to $target was $call_result\n\n";
        //    }
        //} else
        echo $ev_name;
        if ( $ev_name == 'EXECUTE_COMPLETE' ) {
            //my $digit = $e->getHeader("DTMF-Digit");
           // print "Received DTMF digit: $digit\n";
            //if ( $digit =~ m/\D/ ) {a
             //   print "Exiting...\n";
                //if ( $e->getHeader("Job-UUID") == $job_uuid ) {
                $stay_connected = 0;
                //}
            //}
        } else {
      # Some other event
        }
    } else {
    # do other things while waiting for events
        //sleep (1);
    }
}
$event=$esl->sendRecv("api uuid_getvar $uuid target_num");
$ret = $event->getBody();
$esl->disconnect();
Apologies for my newbishness and many thanks for your help so far.
Hoping for an epiphany when I sudddenly understand what I am doing!
Alex
Can anyone help with this? I updated to latest Git, thinking it may have 
been a bug, and still have the same problem, when I try to wait for 
events as in the above code, it stops the playback of the "enter the 
phone number" from happening until after the web server times out.

Logically I can't see a reason for this, is it because you can't use an 
inbound connection activated by calling from curl in the dialplan? If 
this is indeed the case I could try rewriting this for outbound but I 
feel that will be more complex for a relative beginner programmer.

If I have missed some vital or obvious concept feel free to chastise me :-).

Thanks

Alex
