Hi, thanks Brian. 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
