I think the name just threw me for a bit. That, and I probably shouldn't look at unfamiliar code past 10. As a follow up question: how do you envision res_speech_dtmf - which will convert an Asterisk DTMF frame into an appropriate SSML/SRGS/NLSML representation - working with another speech engine? Does it have value as a stand-alone piece of functionality? Regardless, I'd be happy to assist with the Asterisk module development. -- Matthew Jordan Digium, Inc. | Engineering Manager 445 Jan Davis Drive NW - Huntsville, AL 35806 - USA Check us out at: http://digium.com & http://asterisk.org _______________________________________________ asterisk-app-dev mailing list asterisk-app-dev@xxxxxxxxxxxxxxxx http://lists.digium.com/cgi-bin/mailman/listinfo/asterisk-app-dev
