Testing communication between two Tropo clients

README.md

Very simple project to test the problem we're seeing with Tropo clients receiving events for calls they didn't initiate.

In one terminal start the 'answer' script with ruby answer.rb. In the other start the 'dial' script with ruby dial.rb. The dial script correctly sends a dial command and the answer script correctly answers. What's odd is that the answer script gets events for 'ringing' and 'answered'. My understanding is that those events should be sent to the dial script as that's responsible for the call it initiated.

answer.rb

require 'bundler/setup'
require 'blather/client/client'

Blather.logger.level = Logger::DEBUG

client = Blather::Client.setup '[email protected]', '1'

client.register_handler(:ready) do
  puts "Connected ! send messages to #{client.jid.stripped}."
end

client.register_handler(:presence) do |m|
  if m.xpath('//x:offer', 'x' => 'urn:xmpp:rayo:1').any?
    answer_iq = Blather::Stanza::Iq.new(:set, m.from.to_s)
    answer_iq['from'] = m.to.to_s
    Nokogiri::XML::Builder.with(answer_iq) do |xml|
      xml.send "answer_", {"xmlns" => 'urn:xmpp:rayo:1'}
    end
    client.write answer_iq
  end
end

EM.run do
  client.run
end

dial.rb

require 'bundler/setup'
require 'blather/client/client'

Blather.logger.level = Logger::DEBUG

client = Blather::Client.setup '[email protected]', '1'

client.register_handler(:ready) do
  puts "Connected ! send messages to #{client.jid.stripped}."
  
  dial_iq = Blather::Stanza::Iq.new(:set, '127.0.0.1')
  dial_iq['from'] = '[email protected]'
  Nokogiri::XML::Builder.with(dial_iq) do |xml|
    xml.send "dial_", {"xmlns" => 'urn:xmpp:rayo:1', 'to' => 'sip:[email protected]', 'from' => 'sip:[email protected]'}
  end
  client.write dial_iq
end

client.register_handler(:presence) do |m|
end

EM.run do
  client.run
end
