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
That is the purpose of start_dtmf to detect it inband and convert it to 2833. Unless you disabled 2833. /b On Mar 13, 2009, at 3:36 PM, Gabriel Kuri wrote:

thanks, I'll give it a try. I'm assuming this app requires a reasonable amount of additional processing power, particularly on a box with several hundred active channels, as it's basically snooping the rtp stream looking for inband dtmf tones? Gabe Brian West wrote:
