[Freeswitch-users] inband dtmf detection

shoot me if I'm on the wrong track, but is it possible to use the start_dtmf app to do inband dtmf detection and "convert" the inband DTMF to rfc2833, as opposed to using the dtmf detection on a Linksys or Grandstream ATA? the reason I ask is the dtmf detection on these ATAs seems to falsely catch dtmf tones during certain conversations and falsely inject a dtmf tone into the stream (I believe the appropriate term is "talk off"). So I was thinking of setting the ATAs to do inband DTMF rather than the current rfc2833 setting, and having FS do the more reliable dtmf detection instead? Thanks, Gabe
