<p class="MsoNormal"><span style="color:#1F497D">I was trying to figure out how to do this exact change to use rfc2833, none or inband to see if it impacted this issue…I was not sure where to make this change…are you suggesting I remove the line to “spandsp_start_dtmf”
or is dtmf-type an option for spandsp? I did not see any options for spandsp that mention 2833 so I figured this was something someplace else.<o:p></o:p></span></p>

<p class="MsoNormal"><span style="color:#1F497D">I have tried removing the spandsp_start_dtmf and adding setting dtmf-type=rfc2833 followed by start_dtmf and I still see my dialed DTMF digits receiving twice and sometimes three times…sometimes I only get the
digit once (what I would expect when I only press the button once). I have tried removing start_dtmf and leaving the dtmf-type=rfc2833<o:p></o:p></span></p>

<p class="MsoNormal"><span style="color:#1F497D"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D">Is there a debug level or log setting that would confirm if I switch to rfc2833 or inband that freeswitch is indeed working as rfc2833 or inband?<o:p></o:p></span></p>

<p class="MsoNormal">Whenever I have problems with duplicate digits as in the later example above I always get a line with switch_rtp.c like this:<o:p></o:p></p>
<p class="MsoNormal"> <o:p></o:p></p>
<p class="MsoNormal">0da6c076-717f-11e6-a732-0360625ff113 2016-09-02 19:35:22.753724 [DEBUG] switch_rtp.c:6874 RTP RECV DTMF 4:800<o:p></o:p></p>
<p class="MsoNormal"> <o:p></o:p></p>
<p class="MsoNormal">If one of the switch_rtp lines does not show up in the output put that it RECV DTMF the DTMF is recognized properly.
<o:p></o:p></p>
<p class="MsoNormal"> <o:p></o:p></p>
<p class="MsoNormal">Is there an option that I can set to tell the switch_rtp.c to ignore receiving DTMF?
<o:p></o:p></p>
<p class="MsoNormal"> <o:p></o:p></p>
<p class="MsoNormal">I do not know happens that causes some calls to work and some calls to not work.<o:p></o:p></p>
<p class="MsoNormal"> <o:p></o:p></p>
<p class="MsoNormal">I was not sure if when it is intermittent (sometimes 80% get duplicate DTMF, sometimes only 20% get duplicate DTMF) what else to try.
<o:p></o:p></p>
<p class="MsoNormal"> <o:p></o:p></p>
<p class="MsoNormal">I saw this:<o:p></o:p></p>

<p class="MsoNormal">and was not sure if this applied…or where options like:<o:p></o:p></p>
<p class="MsoNormal"><param name="auto-rtp-bugs" value="clear"/><o:p></o:p></p>
<p class="MsoNormal">Were supposed to be placed in the dial plan to get these in the right place. Is this part of the options before you invoke action=spandsp_start_dtmf<o:p></o:p></p>
<p class="MsoNormal"> <o:p></o:p></p>
<p class="MsoNormal">Thanks in advance for any help you can provide.<o:p></o:p></p>
