Hi everyone, I've been able to compile the ESL wrapper for Ruby 1.9.2, however, I'm getting an abnormal behavior with a small script (100% functional with Ruby 1.8.7) which basically opens an ESL socket connection and listens to channel events: The event loop looks like the following: con = ESL::ESLconnection.new('localhost', '8021', 'ClueCon') con.events('plain', 'CHANNEL_ANSWER CHANNEL_HANGUP_COMPLETE CHANNEL_BRIDGE CHANNEL_EXECUTE_COMPLETE') i = 0 EM.run do while (con.connected) e = con.recvEvent() EM.defer do if (!e.nil? && !e.getHeader("variable_medularis_uuid").nil? && !e.getHeader("variable_clicktocall").nil?) on_event(e, con, i) i = i + 1 end end end The problem I'm experiencing is that the event loop seems to be reading events from the socket out of sync. For example, when I answer a call, nothing happens (i.e. no event is processed), however, when I hangup, the CHANNEL_ANSWER event is read from the socket. As you can see, I'm using EventMachine, however, I've also tried Ruby threads and I'm getting the same behavior. Any clues on this issue? Has anyone tried Ruby 1.9.2 successfully with ESL? Thanks!
