Freeswitcher 0.4.4 Released, and welcome Harry
This is a fairly minor bugfix (thanks diegoviela) to fix the Playback app. The 0.4.4 should be available via gem.
Mostly i'm sorry this blog has been so idle, we've been working hard on FSR, FXC, and related components, but much of it on commercial or proprietary projects. In the coming months we'll be using this knowledge to release applications which enhance the functionality of open source telecom.
Thanks to all the new contributors, and welcome to the core team Harry Vandberg. He's pushed development along while we played end user for a few months, we're happy to have him.
FreeSWITCHeR 0.4.0 released. Now Ruby 1.9.1 compat! 1
Well ok, then.
FreeSWITCHeR 0.4.0, The Ruby framework for FreeSWITCH, has been released!
This release includes many bug fixes, thanks to everyone for the emails and/or stopping by our IRC channel, #rubyists on Freenode.
Keep the bug reports and feature requests coming
Most importantly, this release introduces Ruby 1.9.1 compatibility with FreeSWITCHeR.
Enjoy!
More FreeSWITCH ruby love - FXC on the way 1
With FSR well under way and being used both internally and in the wild for FreeSWITCH application development, the next logical step will be a Configurator for FreeSWITCH itself. FreeSWITCH has long lacked the standard Administrator/User configuration available via web or GUI, FXC is intended to allow web interfaces for configuration to be built easily with any Rack application utilizing the FreeSWITCH xml_curl interface. The first pass of FXC will include some Rack middleware which turns FreeSWITCH requests (to /) into easy to organize routes such as /directory/register/internal/1000, /dialplan/public/8885551212, /configuration/acl.conf. The goal is to eliminate the gruntwork of routing by POST variables, exposing clean Rack-app routes up the stack (for ramaze, sinatra, etc). The following is an example with ramaze.
middleware.rb
module FXC
module Rack
class Middleware
def initialize(app)
@app = app
end
def call(env)
r = ::Rack::Request.new(env)
return @app.call(env) unless r.params["section"]
path = r.params["section"] + "/"
path << case path
when "dialplan/"
dp_req(env, r)
when "directory/"
dir_req(env, r)
when "configuration/"
conf_req(env, r)
end
env["PATH_INFO"] << (env["PATH_INFO"].match(%r{/$}) ? path : "/#{path}")
@app.call(env)
end
private
def dp_req(env, r)
s = [r.params["Caller-Context"]]
s << r.params["Caller-Destination-Number"]
s.join("/")
end
def dir_req(env, r)
s = []
if r.params["purpose"]
s << r.params["purpose"].gsub("-","_")
s << r.params["sip_profile"]
elsif r.params["action"] and r.params["action"] == "sip_auth"
s << "register"
s << r.params["sip_profile"]
s << r.params["sip_auth_username"]
elsif r.params["user"]
s << "voicemail"
s << r.params["sip_profile"]
s << r.params["user"]
end
s.join("/")
end
def conf_req(env, r)
s = []
if r.params["key_name"] == "name"
s << r.params["key_value"]
end
s.join("/")
end
end
end
end

module FXC
class Dialplan < Controller
map '/dialplan'
layout :dialplan
def index(*args)
Ramaze::Log.info("Got unhandled dialplan request: " + request.inspect)
not_found
end
def default(number)
Ramaze::Log.info("got default dialplan request for #{number}")
not_found
end
def public(number)
@did = FXC::Did.first(:number.like /#{number.sub(/^1/,'1?')}/)
if @did
@user = @did.user
@targets = @did.targets
Ramaze::Log.info("Routing #{@did.number} to #{@user.dialstring}")
render_view(:index)
else
Ramaze::Log.info("Got public dialplan request for #{number}, but no DID matches: ")
not_found
end
end
end
end
In the FXC::Dialplan controller, each method represents a FreeSWICH dialplan context. Undefined contexts (in this ramaze controller) will fallthrough to the index method and be logged.
Finally, the FreeSWITCH configuration to send requests to above app becomes a single line/single url
conf/autoloadconfigs/xmlcurl.conf.xml
<configuration name="xml_curl.conf" description="cURL XML Gateway">
<bindings>
<binding name="fxc">
<param name="gateway-url" value="http://127.0.0.1:9292/" bindings="configuration|directory|dialplan"/>
</binding>
</bindings>
</configuration>
Next step is completing all the methods available for each binding type (configuration, dialplan, directory). Once complete FreeSWITCH web config on Rack should follow rapidly. That will be the “Look Ma, No XML” FXC release (TBA).

Ruby Freeswitch Application Programming Interface (ESL Alternative)
freeswitcher (FSR) is a ruby library for communicating with FreeSWITCH through its event socket interface. FreeSWITCH ruby integration in the core just doesn’t work with the thread models of either 1.8 or 1.9. On the other hand; FSR, built on ruby eventmachine, can manage more than one instance of FreeSWITCH at a time.
Using the freeswitcher gem, 2 minute tutorial
This program will play a smooth wav file and read the DTMF tones entered by the caller. It simply logs the received digits to the info facility (you should see it on stdout)
require "rubygems"
require "fsr"
require "fsr/outbound"
class GetDigits < FSR::Listener::Outbound
def session_initiated
exten = session.headers[:caller_caller_id]
answer do
read("/path/to/smooth.wav") do |read_var|
FSR::Log.info("Received #{read_var} from #{exten}")
end
end
end
end
FSR.start_oes! GetDigits, :port => 8084, :host => "127.0.0.1"In order to use the above script, add the following in your FreeSWITCH dialplan. You can save it as 00sockettest.xml in conf/dialplan/default/ if you’re using the stock FreeSWITCH configuration.
<include>
<extension name="8084">
<condition field="destination_number" expression="^8084$">
<action application="set" data="continue_on_fail=true" /> <!-- we still need this to continue if bridging times out -->
<action application="set" data="call_timeout=5" />
<action application="socket" data="127.0.0.1:8084 sync full"/>
</condition>
</extension>
</include>Then reloadxml on FreeSWITCH, make sure the GetDigits listener is started, and call 8084 on a phone registered to FreeSWITCH.
This is only the Outbound Event Socket handler for FreeSWITCH in ruby. Other interfaces freeswitcher includes are the Inbound Event Socket handler and a CommandSocket, which allows any api or bgapi command. See the docs for the full scoop.
