[Freeswitch-users] perl ESL outbound socket, no DTMF if not async ???

[Giovanni Maruzzelli]

Ciao FreeSWITCHers,


on FS 1.4.18:

using perl ESL outbound socket, I see FS receives DTMF 2833 only when
socket is declared "async" in dialplan.

NB: not only the outbound socket does not receives DTMF events, is
FreeSWITCH itself that does not receives DTMFs.

Is this correct? Is this the expected behavior?

If I delete "async" from dialplan, DTMFs are not received

es:
<action application="socket" data="127.0.0.1:8040 async"/> works,
while with
<action application="socket" data="127.0.0.1:8040"/> no DTMFs at all.

====

btw, this is an example of outbound_socket in perl ESL

#!/usr/bin/perl
require ESL;
use IO::Socket::INET;
my $ip = "127.0.0.1";
my $sock = new IO::Socket::INET ( LocalHost => $ip,
                                  LocalPort => '8040',
                                  Proto => 'tcp',
                                  Listen => 1,
                                  Reuse => 1 );
die "Could not create socket: $!\n" unless $sock;

for(;;) {
    my $new_sock = $sock->accept();
    my $pid = fork();
    if ($pid) {
        print "New child pid $pid created...\n";
        close($new_sock);
        next;
    }

    my $fd = fileno($new_sock);
    my $con = new ESL::ESLconnection($fd);
    my $info = $con->getInfo();
    my $uuid = $info->getHeader("unique-id");

    printf "Connected call %s, from %s\n", $uuid,
           $info->getHeader("caller-caller-id-number");

    $con->sendRecv("myevents $uuid");

    $con->setEventLock("1"); # need this for forcing execution order on
async, has no effect if no "async" in dialplan
    $con->execute("sleep","500");
    $con->execute("answer");
    $con->execute("sleep","500");
    $con->execute("playback",
                  "ivr/ivr-welcome_to_freeswitch.wav");
    $con->execute("sleep","500");
    $con->execute("playback",
                  "ivr/ivr-finished_pound_hash_key.wav");

    while($con->connected()) {
        my $e = $con->recvEvent();
        if ($e) {
            my $name = $e->getHeader("event-name");
            print "EVENT [$name]\n";
            if ($name eq "DTMF") {
                my $digit = $e->getHeader("dtmf-digit");
                my $duration = $e->getHeader("dtmf-duration");
                print "DTMF digit $digit ($duration)\n";
                $con->execute("hangup");
            }
        }
    }
    print "BYE\n";
    close($new_sock);
}
