I am getting an increasing number of issues where the dtmf tones being received appear to get doubled up. So I enter 1234 on my telephone keypad and 11223344 appears to be received in the buffer when calling getDigits. This doesn’t happen all the time but often enough to be a problem. All the calls in to my system are forwarded on to me directly via SIP from a major UK telecoms provider that terminates numbers for us.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Can anyone suggest what dtmf settings I may have got wrong that would cause this phenomenon or any suggestions how I can go about fixing it?<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>I’m using …<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal><span style='font-size:9.0pt;font-family:"Courier New";color:blue;background:white;mso-highlight:white'><</span><span style='font-size:9.0pt;font-family:"Courier New";color:#A31515;background:white;mso-highlight:white'>action</span><span style='font-size:9.0pt;font-family:"Courier New";color:blue;background:white;mso-highlight:white'> </span><span style='font-size:9.0pt;font-family:"Courier New";color:red;background:white;mso-highlight:white'>application</span><span style='font-size:9.0pt;font-family:"Courier New";color:blue;background:white;mso-highlight:white'>=</span><span style='font-size:9.0pt;font-family:"Courier New";color:black;background:white;mso-highlight:white'>"</span><span style='font-size:9.0pt;font-family:"Courier New";color:blue;background:white;mso-highlight:white'>start_dtmf</span><span style='font-size:9.0pt;font-family:"Courier New";color:black;background:white;mso-highlight:white'>"</span><span style='font-size:9.0pt;font-family:"Courier New";color:blue;background:white;mso-highlight:white'> /></span><span style='font-size:9.0pt;font-family:"Courier New";color:blue'><o:p></o:p></span></p><p class=MsoNormal><span style='font-size:9.0pt;font-family:"Courier New";color:blue'><o:p> </o:p></span></p><p class=MsoNormal>In my dialplan.
