<span style='font-family:Verdana'><span style='font-size:12px'>It appears that we cannot use carrier's RFC2833 sequence as it's missing up to 50% of digits sent to them by the original caller. And this is not happening on the same system with 2 other carriers.<br />
<br />
Peter and Michael, thank you very much for your help and explanations.<br />

                That's kinda sorta what he's saying. A better way of saying it is this: if your carrier sends you RFC2833 DTMFs then you don't even need to turn on dtmf detect stuff. Unless there is a compelling reason to go in-band I'd say just use RFC2833 and be done with it.<br />
