Hi, Any help or suggestion regarding my previous post. Especially
"I also noted that, if I don't receive any events, especially
"SERVER_DISCONNECTED", then the connection is in established state,
but once I receive the "SERVER_DISCONNECTED" event, the connection
is closed. Is it correct??"
Here is the program by which I confirmed the above!
require ESL;
use IO::Socket::INET;
my $ip = "192.168.1.222";
my $sock = new IO::Socket::INET ( LocalHost => $ip, LocalPort =>
'8447', Proto => 'tcp', Listen => 2, Reuse => 1 );
die "Could not create socket: $!\n" unless $sock;
my $con;
my $type = "user/";
for(;;) {
# wait for any client to connect, a new client will get
connected when a new call comes in the dialplan.
my $new_sock = $sock->accept();
# Do fork and let the parent to wait for more clients.
my $pid = fork();
if ($pid) {
close($new_sock);
next;
}
# Extract the host of the client.
my $host = $new_sock->sockhost();
# file descriptor for the socket.
my $fd = fileno($new_sock);
print "Host name is $host\n";
# Create object for the ESL connection package to access the
ESL functions.
$con = new ESL::ESLconnection($fd);
# Gets the info about this channel.
my $info = $con->getInfo();
my $uuid = $info->getHeader("unique-id");
printf "Connected call %s, from %s to %s\n", $uuid, $info-
>getHeader("caller-caller-id-number"), $info->getHeader("caller-
destination-number");
# Answer the channel.
$con->execute("answer");
# Set the event lock to tell the FS to execute the
instructions in the given order.
$con->setEventLock("true");
# Play a file & Get the personal number from the user.
$con->execute("playback","/usr/local/freeswitch/sounds/en/us/
callie/ivr/8000/ivr-welcome_to_freeswitch.wav");
$con->execute("hangup");
while($con->connected())
{
my $e=$con->recvEvent();
my $ename=$e->getHeader("Event-Name");
print $e->serialize();
print "$ename\n";
print "Connection exists\n";
sleep(1);
}
print "Bye
\n------------------------------------------------------------------
\n";
close($new_sock);
}
I've not registered for any events.
In the above program I'm receiving the SERVER_DISCONNECTED event.
Output when receiving event:
Host name is 192.168.1.222
Connected call 022b79f8-d8c0-11de-8d50-596fac84e59e, from 1000
to 9097
Event-Name: SERVER_DISCONNECTED
SERVER_DISCONNECTED
Connection exists
Bye
When I comment the recvEvent line, I got the following output.
Host name is 192.168.1.222
Connected call 65b7f64a-d8c0-11de-8d50-596fac84e59e, from 1000
to 9097

I've tried the following program as per the suggestion that you've
told. But it seems, no success. Once the connection is closed, I
created a new connection and I send originate to originate a new
call. But it is not working.

$con->execute("answer");
$con->setEventLock("true");
my $number=$con->execute("read","2 4 /usr/local/freeswitch/
sounds/en/us/callie/conference/8000/conf-pin.wav accnt_number 5000

while($con->connected())
{
my $e=$con->recvEvent();
my $ename=$e->getHeader("Event-Name");
my $app=$e->getHeader("Application");
if($ename eq "CHANNEL_EXECUTE_COMPLETE" and $app eq
"read")
{
my $num=$e->getHeader
("variable_accnt_number");
print "$num\n";
$con->execute("hangup");
}
}
if(!$con->connected())
{
print "Connection not exists\n";
$con = new ESL::ESLconnection($fd);
$con->api("originate","user/1000 &park()");
print "Hai\n";
}
print "Bye
\n------------------------------------------------------------------
\n";
close($new_sock);
}
Output:

The freeswitch log is in

I also noted that, if I don't receive any events, especially
"SERVER_DISCONNECTED", then the connection is in established state,
but once I receive the "SERVER_DISCONNECTED" event, the connection
is closed. Is it correct??

or open a new outbound connection at the end of your script so you
can send your originate command.
Since the channel hanging up will close your existing connection
since it's only an outbound single session socket.

Hi,
I'm using perl ESL to control the call in freeswitch.
I'm having the following scenario, but not able to get it right.
Dialplan:
<extension name="outbound_soc">
<condition field="destination_number" expression="^9097$">
<action application="set" data="continue_on_fail=true"/>
<action application="socket" data="192.168.1.222:8447
async full"/>
</condition>
</extension>
1. User A calls to an extention (1000).
2. My ESL program will be running, and it answers the call.
3. Then the program will get a number from the user.
4. It will hangup the call.
5. The program has to call to the number that was given by the user.
In the above scenario, I was able to do until the 4th step. After
hangup the call, if I say originate it is not working.
Any ideas on how to do this in ESL.
I want to make sure I understand what the script is supposed to be
doing. The caller will key in a phone number to your script and your
script will collect those digits. The script will then hangup on the
caller and originate a completely new call? Perhaps you could use
sched_api to schedule a new originate command for a few seconds into
the future and then hangup?
