<div dir="ltr"><div><div><div>Hello.<br><br></div>We have encountered a problem. We use bind_digit_action application to activate a number of features. To still have ability to pass DTMF signals between A_leg and B_leg, we use send_dtmf application. This is a part of our dialplan.<br> <br>&lt;extension name=&quot;Bind_DTMF_action&quot;&gt;<br>    &lt;condition field=&quot;destination_number&quot; expression=&quot;^DTMF_CALL_CONTROL$&quot;&gt;<br>      &lt;action application=&quot;bind_digit_action&quot; data=&quot;dtmf_call_control,*1,exec:execute_extension,attented_xfer XML ${context},both,self&quot;/&gt;<br>      <br>      &lt;action application=&quot;bind_digit_action&quot; data=&quot;dtmf_call_control,~^\d,exec:execute_extension,send_dgts XML ${context},both,peer&quot;/&gt;<br>      &lt;action application=&quot;digit_action_set_realm&quot; data=&quot;dtmf_call_control&quot;/&gt;<br>    &lt;/condition&gt;<br>  &lt;/extension&gt;<br><br><br>&lt;extension name=&quot;Send_DTMF&quot;&gt;<br>&lt;condition field=&quot;destination_number&quot; expression=&quot;^send_dgts$&quot;&gt;<br>&lt;action application=&quot;send_dtmf&quot; data=&quot;${last_matching_digits}&quot;/&gt;<br>&lt;/condition&gt;<br>&lt;/extension&gt;<br><br><br>All work well but one  snag - our customers from time to time complain inability to interact whith IVR. During debugging we have discovered that  Freeswitch generates DTMF signals with volume = 13.<br>The problem is that a lot of popular PBX and call managers (for example Cisco UCM) do not recognize DTMF with such low volume. <br>Is it possible to set this value in freeswitch as we need or this parameter is not configurable? <br>-- <br><div class="gmail_signature">WBR<br></div><div class="gmail_signature">Alex M.<br></div>
