Mike, thanks for following this up . . . . . Not having the faintest idea what those settings might do, I never thought of changing them and see what difference it made, but you prompted me to try that.... I've still no idea what "RTP Payload Type" is, but changing it makes no difference to my problem. However, DTMF level (the "DTMP" was a typo in my earlier message), which I'm guessing is a kind of volume setting (?) DOES make a difference. Setting it to different values makes the error go away, it's currently set at "1" (from "0") which seems to have been enough to get rid of the problem. Strange that the problem only affected one digit ("0"), but maybe something was just on a limit somewhere - maybe the phone has an issue with certain frequencies. Anyway, a simple work around, if only I'd had the sense to try that earlier - thanks a lot for the prompt ! regards Dave ----- Original Message ----- From: Michael Jerris To: freeswitch-users@lists.freeswitch.org Sent: Wednesday, March 10, 2010 9:56 AM Subject: Re: [Freeswitch-users] [ERR] switch_rtp.c:2196FailedDTMFpayloadcheck. curious what happens if you change the level or payload type int hat config below as well.

Hi Mathieu, if you tell me how to generate one, I'll do it now ? regards Dave ----- Original Message ----- From: Mathieu Rene To: freeswitch-users@lists.freeswitch.org Sent: Wednesday, March 03, 2010 8:09 PM Subject: Re: [Freeswitch-users] [ERR] switch_rtp.c:2196 Failed DTMFpayloadcheck. I don't recall any rfc2833 changes in the past 2 weeks. I would like to see a packet capture of those bogus rtp packets though.

The device is a Thomson ST2030 which has a basic listing on the Interop Wiki page, but does not specifically mention rfc2833 (although rtp is marked as "not tested"). I have not seen this message before while running the FS version that I'm currently using 16543 - yes, I know that this is a few weeks old and I will update and/or raise a bug once I've upgraded, but it would be nice to know if anyone else sees problems with this phone, regards Dave ----- Original Message ----- From: Brian West To: freeswitch-users@lists.freeswitch.org Sent: Wednesday, March 03, 2010 7:50 PM Subject: Re: [Freeswitch-users] [ERR] switch_rtp.c:2196 Failed DTMF payloadcheck. It usually means your device can't do rfc2833 correctly and needs to have a bug opened so they can fix it. /b On Mar 3, 2010, at 1:39 PM, Dave Stevenson wrote: It appears in response to keypad events during voicemail retrieval, the prompts were actioned correctly, but I was wondering what the message actually means ? -------------------------------------------------------------------- _______________________________________________ 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 ------------------------------------------------------------------------ _______________________________________________ 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 _______________________________________________ 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
