Interesting idea, but I don't think so. Will check...
The model of cellphone should be irrelevant for these types of issues. However, different cellular networks handle DTMF differently. If you see different results with different phones, is it because they are on different networks.

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?
