[Freeswitch-users] Unreliable DTMF

I've got an application that doesn't seem to work well with DTMF coming
in (supposedly using rfc2833) from some phones - notably Samsung S3s.
I have told my carrier to use rfc2833.
I have put dtmf-type="rfc2833" into my SIP profile.
I see "a=fmtp:101 0-16" in the session progress message
I was wondering what this message "Activate Buggy RFC2833 Mode" means!
When a normal user hits a DTMF key, we get this in the log:
2013-07-25 13:26:19.308267 [DEBUG] switch_rtp.c:3917 RTP RECV DTMF 1:744
2013-07-25 13:26:19.308267 [DEBUG] switch_channel.c:471 RECV DTMF 1:744
Does this all indicate that rfc2833 is working?!
Anyone else had trouble with S3s?
