Actually I don't think this issue is exactly as it seems.  I have also 
seem the issue you are describing.  But at the same time on the same 
server I have other ATA's connected that are using RFC2833 and they 
function properly (ie DTMF words AOK).

I think the * VM issue is actually with the SIP info method for DTMF, 
not inband.

Another though I have is that if you are calling from the FXS through 
the FXO on your SPA3000 (whem lot of contractions), shouldn't you be 
able to reinvite and get * out of the media path entirely?  If the DTMF 
still fails it's not Asterisks fault.

I do also have an issue with RFC2833 not working properly on one ATA 
(wellgate 3701a),  but I kind of presume that to be wellgates 
implementation issue.

I would think that if this DTMF issue was as plainly obvious as this 
thread suggests it would have been fixed long ago?  I hope?
