From: freeswitch-users-bounces@lists.freeswitch.org [mailto:freeswitch-users-bounces@lists.freeswitch.org] On Behalf Of Michael Collins Sent: 26 March 2012 18:39 To: FreeSWITCH Users Help Subject: Re: [Freeswitch-users] Strange DTMF Tones On Inbound Calls On Mon, Mar 26, 2012 at 3:01 AM, Daniel Knaggs <Daniel.Knaggs@realitysolutions.co.uk<mailto:Daniel.Knaggs@realitysolutions.co.uk>> wrote: OK, call recording has been setup – waiting for it to happen now. Interestingly, before I issue the “record_session” application (and of course the “RECORD_*” variables) I had to execute “ring_ready” then “pre_answer” otherwise the caller gets silence (changing the order of those two commands results in silence). I find it odd that just doing a pre_answer wouldn't be sufficient. A pre_answer will send a 183 w/SDP whereas ring_ready simply sends a 180. In any case, I'm glad you got your recordings. I also find it curious that only the "letter" DTMFs are being detected. Let us know if you actually hear those tones in the audio stream. -MC
