Launching a call with an inbound event socket connection
Using an inbound event socket connection to launch a call is a common requirement for some applications, such as outbound IVRs. In a case like this it is advantageous to handle the generating of the calls in a non-blocking manner using the ESL connection object's bgapi()
method. This recipe discusses how to use the bgapi()
method with the corresponding "Background-Job UUID".
Getting ready
Be sure that you have configured ESL for your system and that you have followed the steps in Establishing an inbound event socket connection earlier in this chapter. The examples here are written in Perl but the principles apply to any ESL-enabled language. Of course, you will need a text editor and a SIP phone registered to your FreeSWITCH server in order to test this example.
How to do it...
Start by creating the new script:
Create the file
scripts/ib_bgapi.pl
in a text editor and add these lines:#!/usr/bin/perl use strict; use warnings; require...
