The vast majority of IVR platforms (mainly VoiceXML) permit handling DTMF in a consistent manner to speech recognition, that is by way of a DTMF grammar. Asterisk, to my knowledge, does not currently include an SRGS-based DTMF recognizer. FreeSWITCH recently got one as part of mod_rayo, and Chris Rienzo has stated that he believes making a majority of this into a library general enough to be used in Asterisk also would be plausible, leaving limited integration effort in Asterisk. It is interesting to me in order to simplify the implementation of Adhearsion atop Asterisk, since right now we have this in Ruby based on AMI DTMF events. Is there any appetite among the Asterisk core team to investigate the addition of this to Asterisk core or as a module? If this gets agreement in principle, I'd love to talk more thoroughly about the kind of API that would be most useful for us, and how we can move forward with specification and implementation. -------------- next part -------------- An HTML attachment was scrubbed...
