Correctly. This is the general usage for any ESL connection, regardless of the client's language.<div><br></div><div>Setting your own UUID is optional, but does avoid a race condition where you might miss events for the call before you manage to subscribe for them.</div>
<div><br></div><div>Just another note: use the originate API and execute it with the bgapi ESL command - the command will return instantly and let you collect the events before the orginate succeeds/fails.</div><div><br>
</div>
<div>Also connect in async mode.</div><div><br></div><div>If you're initiating multiple calls I also highly recommend you write your system in such a way that worker script(s) connect via ESL and keep persistent connections open. Originate multiple calls through the same socket. It'll result in fewer connections open which'll be better load-wise, and since connections will already be open will save a few ms on starting the call up. On the client it means fewer processes running, so fewer context-switches therefore will scale better client-side as well as server-side. And of course there's a limit on the number of processes too.</div>

<br>
1) Establish the connection to FreeSWITCH, you'll be using the event socket on inbound mode<br>
2) Start listening for the events you want to capture (send the 'event plain all' or 'event plain CHANNEL_ANSWER DTMF CHANNEL_HANGUP ...' command)<br>
3) Create an uuid (by sending the create_uuid command) so you can identify which call you'll be listening events for<br>
4) Add a filter for this uuid, so you'll only receive events for this call over this connection (filter Unique-ID + uuid)<br>
5) originate the call: {origination_uuid= + uuid}sofia/internal/NXX@GATEWAY<br>

Subject: [Freeswitch-users] Make a call with Perl<br>
<br>
Hi All<br>
<br>
I try to make a Perl Script which calls a certain external Phone number.<br>
It then should wait until someone picks up and play a sound file The user on the other end then needs to confirm the call with a pin Then another sound file should be played and the the call should be terminated.<br>
<br>
I tried several ways with ESL and originate. But I allays end up with a call I have no control over. I can read DTMF but can not hang up the call or play a second file.<br>
<br>
I think I am going in to a wrong direction.<br>
<br>
Any hints ?<br>
<br>
Regards<br>
<br>
Matthias<br>
