For testing, that would do fine.

That would cause you a bad loop. Like I said, you may wish to limit the number of restarts just in case you end up misdialing a system that is just repeating it's menu. > >Shouldn't be a problem.

The original use(I think) was to hook sphinx up to asterisk in a way that didn't cause licensing issues. In this case, you can use the audio coming in on file descriptor 3 to run your own DSP. Of course, with your TTS choice, I guess you will also being executing a text to speech command to file then stream the file. -- Steven Critchfield <[EMAIL PROTECTED]> _______________________________________________ Asterisk-Users mailing list [EMAIL PROTECTED] http://lists.digium.com/mailman/listinfo/asterisk-users
