What is the purpose of FreeSWITCH's mod_esl?

^{There is [another question][1] trying to figure out the connection between mod_event_socket and the Event Socket Library (ESL).}

The [Event Socket Library][2] itself is a C library ([libesl][3]) that can be used to build external C applications to control FreeSWITCH via its [event system][4].

As far as I understand, [mod_esl][5] is only a FreeSWITCH module wrapper around [libesl][3], used to extend programming languages with the same functionality (i.e., to control a FreeSWITCH instance). The [documentation][5] doesn't mention this, but basing this assumption on the quoted sources below, and on the fact that I couldn't find anyone ever using it directly (i.e., found no mailing list question, nothing on slack, no SO questions, no blog posts, [the books][6] also barely mention it, and so on). Are there any other use cases that I'm missing?

Attila Gulyas 10:48 AM hi, if we'd like to have callers control audio playback during a call, we would use the relevant mod_commands (such as uuid_fileman perhaps?), bound to DTMF key strokes (like here: https://lists.freeswitch.org/pipermail/freeswitch-users/2013-January/091183.html ), right? For context: this is for a system for blind users to listen to articles recorded by volunteers.

[PostgreSQL must also be configured to allow remote connections][1], otherwise the connection request will fail, even if all firewalls rules are correct and PostgreSQL server is listening on the right port.

Steps

1. IP addresses

To connect from your laptop, you will need the public IP address of your laptop, and that of the Google Compute Engine (GCE) instance.

1.1 Your laptop's public IP address
