Re: [Freeswitch-users] Double-dtmf detection in IVR when a call is routed through FreeSWITCH
Did a few TCP dumps, and before, I was seeing explicit DTMF packets coming out of my FreeSWITCH machine. Removing the only things I could find that had to do with 2833 in my internal and external sip_profiles (namely rfc2833-pt), I find that I don't see any mention of switch_rtp.c sending any DTMF packets, nor do I see any in the TCP dump. This still hasn't solved my problem. I tested again, and with 'start_dtmf', I get an audible hiccup in the audio when DTMF occurs. When I don't use 'start_dtmf', the hiccup goes away. Is there anything else that I should be turning off on FreeSWITCH to avoid this hiccup? -Drew On Wed, May 27, 2009 at 12:11 PM, Drew Ozier wrote: > The AudioCodes machines are always a bit of a nuisance to get acting the > way I want, but I think I have them sending all DTMF in-band.

Re: [Freeswitch-users] Double-dtmf detection in IVR when a call is routed through FreeSWITCH
I'm sorry, far side meaning what exactly? The call flow is as follows: TDM T1 -> AudioCodes Mediant 1000 -> FreeSWITCH -> AudioCodes Mediant 1000 -> TDM T1 FreeSWITCH gets an inbound SIP call and makes an outbound SIP call back to the Mediant 1000, bridging the two calls. The Mediant 1000 sends the call back out the T1 and that goes to my customer's IVR. I have no control over anything after it leaves my T1. Is there some other piece of information I'm missing? Do you want my sip_profiles? -Drew On Wed, May 27, 2009 at 11:30 AM, Brian West wrote: > This is what starts the inband detector.. what is the far side? > > /b > > > On May 27, 2009, at 10:25 AM, Drew Ozier wrote: > > > > > Brian West > br...@freeswitch.org > > -- Meet us at ClueCon! http://www.cluecon.com > > > > > > ___ > Freeswitch-users mailing list > Freeswitch-users@lists.freeswitch.org > http://lists.freeswitch.org/mailman/listinfo/freeswitch-users > UNSUBSCRIBE:http://lists.freeswitch.org/mailman/options/freeswitch-users > http://www.freeswitch.org > > ___ Freeswitch-users mailing list Freeswitch-users@lists.freeswitch.org http://lists.freeswitch.org/mailman/listinfo/freeswitch-users UNSUBSCRIBE:http://lists.freeswitch.org/mailman/options/freeswitch-users http://www.freeswitch.org

Re: [Freeswitch-users] Double-dtmf detection in IVR when a call is routed through FreeSWITCH
To clarify, I'm not running the IVR. I have a TDM T1 that comes in to an AudioCodes Mediant 1000 (SIP Gateway) which goes to a FreeSWITCH machine. I receive calls coming in off the T1 which goes through my Mediant 1000 which goes to my FreeSWITCH machine which makes an outbound call back through the Mediant 1000 to an IVR (bridging the inbound and outbound calls). I have (supposedly) configured the AudioCodes Mediant 1000 to pass the DTMF in-band, because I want to minimize the amount of modifications I make to the audio stream going through my system. I also want to be able to log when DTMF events occur for analysis purposes. If I do not have start_dtmf, then FreeSWITCH does not show me any DTMF in the logs, but when I have it on, it will. Here's a DTMF event in my FreeSWITCH logs: (I changed the debug message to a notice and added the callId and the nano time of the event) 2009-05-26 16:02:05 [NOTICE] switch_ivr_async.c:996 inband_dtmf_callback() 348323 61182225861200042...@10.1.10.10 DTMF DETECTED: 5 2009-05-26 16:02:05 [DEBUG] switch_rtp.c:1322 do_2833() Send start packet for [5] ts=1217893935 dur=160/160/2000 seq=55199 2009-05-26 16:02:05 [DEBUG] switch_rtp.c:1258 do_2833() Send middle packet for [5] ts=1217893935 dur=320/320/2000 seq=55200 2009-05-26 16:02:05 [DEBUG] switch_rtp.c:1258 do_2833() Send middle packet for [5] ts=1217893935 dur=480/480/2000 seq=55201 2009-05-26 16:02:05 [DEBUG] switch_rtp.c:1258 do_2833() Send middle packet for [5] ts=1217893935 dur=640/640/2000 seq=55202 2009-05-26 16:02:05 [DEBUG] switch_rtp.c:1258 do_2833() Send middle packet for [5] ts=1217893935 dur=800/800/2000 seq=55203 2009-05-26 16:02:05 [DEBUG] switch_rtp.c:1258 do_2833() Send middle packet for [5] ts=1217893935 dur=960/960/2000 seq=55204 2009-05-26 16:02:05 [DEBUG] switch_rtp.c:1258 do_2833() Send middle packet for [5] ts=1217893935 dur=1120/1120/2000 seq=55205 2009-05-26 16:02:05 [DEBUG] switch_rtp.c:1258 do_2833() Send middle packet for [5] ts=1217893935 dur=1280/1280/2000 seq=55206 2009-05-26 16:02:05 [DEBUG] switch_rtp.c:1258 do_2833() Send middle packet for [5] ts=1217893935 dur=1440/1440/2000 seq=55207 2009-05-26 16:02:05 [DEBUG] switch_rtp.c:1258 do_2833() Send middle packet for [5] ts=1217893935 dur=1600/1600/2000 seq=55208 2009-05-26 16:02:05 [DEBUG] switch_rtp.c:1258 do_2833() Send middle packet for [5] ts=1217893935 dur=1760/1760/2000 seq=55209 2009-05-26 16:02:05 [DEBUG] switch_rtp.c:1258 do_2833() Send middle packet for [5] ts=1217893935 dur=1920/1920/2000 seq=55210 2009-05-26 16:02:05 [DEBUG] switch_rtp.c:1258 do_2833() Send end packet for [5] ts=1217893935 dur=2080/2080/2000 seq=55211 2009-05-26 16:02:05 [DEBUG] switch_rtp.c:1258 do_2833() Send end packet for [5] ts=1217893935 dur=2080/2080/2000 seq=55212 2009-05-26 16:02:05 [DEBUG] switch_rtp.c:1258 do_2833() Send end packet for [5] ts=1217893935 dur=2080/2080/2000 seq=55213 Does the fact that switch_rtp is sending packets mean that FreeSWITCH is sending out-of-band DTMF as well as recognizing the in-band?

[Freeswitch-users] Double-dtmf detection in IVR when a call is routed through FreeSWITCH
I've got a configuration where I receive inbound calls and dial out to a pre-determined 800-number based on the DNIS of the call. I set and have everything set up so that DTMF only comes to me via inband. When I'm providing DTMF data to the IVR, it will recognize a single keypress as a double-tap. My FreeSWITCH logs only contain one DTMF entry, but when I listen to the receiving end of the call, I can hear a hiccup in the DTMF tone that is getting played. When I do not use 'start_dtmf', this problem goes away. I need inband DTMF detection, but I can't have it messing up the audio stream.

[Freeswitch-users] Problem listening to PCMU and ul recordings
Hi, I've been using the record_session feature and wish to use PCMU or ul audio format, but when I try to play back the audio in either format, it sounds high-pitch and fast as if it is playing back at 2x speed. I looked at the waveform recorded in PCMU and ul versus what it looks like when I record as wav, and it seems like it is only recording every-other sample (which would explain the pitch and speed). My vars.xml is set to PCMU as the global codec pref and the outbound codec pref. I am recording in stereo (one channel per leg of the call), but I'm not messing with any other recording parameters. Incedentally, the wav sounds just fine, but I'd prefer an 8-bit mulaw audio file, because I'm getting calls off a T1 (actually off of an AudioCodes Mediant 1000 that is converting the T1 to SIP for me), and I'd like to record precicely what is coming off the wire. I'd be happy to send any configuration files, I'm just currently at a loss for how to proceed.
