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

curious what happens if you change the level or payload type int hat config below as well.

Some more info . . .
The error only seems to occur when a "0" is entered.
Looking at the Phone config, the RFC2833 options are :-
In Band
Out of Band (RFC2833) - currently selected
SIP Info
RTP Payload Type (96-127) - 96 currently selected
RTP DTMP Level (0-63) - 0 Currently selected

Hi Mathieu,
if you tell me how to generate one, I'll do it now ?

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.

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

It usually means your device can't do rfc2833 correctly and needs to have a bug opened so they can fix it.

It appears in response to keypad events during voicemail retrieval, the prompts were actioned correctly, but I was wondering what the message actually means ?
