The $fd variable is a file descriptor for the socket connection that is opened. It is passed to the new method of the ESL::ESLconnection object class to ensure that the $con object communicates with the correct TCP stream from FreeSWITCH. Once we have the connection object ($con), we can get some information from it, with these lines:

my $info = $con->getInfo(); my $uuid = $info->getHeader("unique-id");

The $info object is a representation of the initial burst of information that FreeSWITCH sends to the script when the socket connection is first established. The $uuid variable is populated with the call leg's UUID, which is found in the unique-id header of the $info object.

This line is important for outbound socket connections:

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