We've actually had issues with Flowroute in the past where DTMF was a constant issue. My best suggestion for course of action is find another provider. NexVortex is pretty solid all around. They also had the quickest recourse for when GNAPS went bottoms up last month and sent pretty much all VoIP traffic in New England into a tailspin. <br>

</div></div>I have seen this before. Upon careful analisys we saw that the far end<br>
was sending the digits in RFC2833 plus SIP INFO (or Inband, I can't<br>
remember). Thus Asterisk detected double digits. The solution was to<br>
ask the remote end to only send RFC2833.<br>
