As we move another step closer to our 2nd beta, we added a few more features this week.

1) The channel variable RECORD_STEREO=true will make the record_session application record a stereo file with the read and write streams in seperate channels. For the more seasoned develope this also means the media bugs have a capability to return audio in mixed or stereo form for other applications as well.

2) The addition of mod_fifo. This module makes it possible to park many calls in a fifo queue and unpark them in the order in which they were received. This will make it possible to make parking and call distribution applications. The module sends events detailing stages of callflow as well as an api interface command to generate a full report of the call state. And is purely dynamic with no configuration necessary to support an infinite amount of fifo queues.
