In a multi server setup. It might be interesting to query a remote FreeSWITCH™ to gather informations. This module will include different capability to do just that.

single_esl API

This api do a passtruth of an API request to a remote server and return the result.

single_esl [<user>]|<password> <host>[:<port>] <timeout> <remote api> <arguments>

Simplification

To make things simpler for day to day use, you can use feature from mod_abstraction. Here an example:

<api name="remote_user_password" syntax="<id>@<domain>" parse="(.*)" destination="single_esl" argument="|ClueCon 192.168.1.2 5000 user_data $1 var effective_caller_id_name"/>

Now you only need to call remote_user_password(1000@default) to get information from the remote  FreeSWITCH™.
