FCS: FreeSWITCH Command Socket

FCS is a lightweight api wrapper for FreeSWITCH's event socket.

Installation

Add this line to your application's Gemfile:

gem 'fcs'

And then execute:

$ bundle

Or install it yourself as:

$ gem install fcs

Usage

Using FCS is easy and intuitive. After initializing, dispatch commands to FreeSWITCH using the .dispatch! method. See the examples below.

Initializing

fs = FCS.new(
  remote_host: 'localhost',
  remote_port: '8021'
)

Authorizing

fs.auth('ClueCon').dispatch!

Examples

FCS is basically a naive command builder for freeSWITCH. You build commands by chaining method calls that match FreeSWITCH's mod_commands like so:

request = fs.api.originate 'sofia/mydomain.com 1000'
response = request.dispatch!

This is equivalent:

response = fs.api.originate('sofia/mydomain.com', '1000').dispatch!

Both these commands result in this api command being sent to FreeSWITCH:

api originate sofia/mydomain.com 1000

These two commands are also equivalent:

fs.api.uuid_getvar('fs_id', 'varname').dispatch!
fs.api.uuid_getvar('fs_id').varname.dispatch!

This flexible syntax allows you to build commands in a very natural way that mimics FreeSWITCH's command syntax.

A more complex example:

fs.sendmsg(fs_id).call_command(:execute).execute_app_name(:playback).execute_app_arg('/tmp/sound.wav').loops(-1).event_lock(true)

The sendmsg command takes an optional uuid parameter. Since execute is so common, there's a helper method that shortens the above to:

fs.sendmsg(fs_id).execute(:playback, '/tmp/sound.wav').loops(-1).event_lock(true)

Pretty much any api method should work out of the box. A few more examples:

fs.api.sched_api('+20').originate('sofia/external &echo()').dispatch!
fs.api.uuid_send_dtmf(fs_id, 'W0W011W@250')
fs.api.uuid_kill(fs_id, 'NORMAL_CLEARING')
fs.api.sched_broadcast('+20', fs_id, 'commercial.wav').aleg
fs.bgapi.originate 'sofia/mydomain.com'    

Calling dispatch! at the end of the chain is necessary in order to dispatch the command to FreeSWITCH. Otherwise you'll get back a Request object.
