Would need a feature request on JIRA to add a param or variable to control dtmf volume then wait for someone to decide to code it or maybe offer a bounty. On Fri, Dec 18, 2015 at 7:43 AM, Алексей Морозов <a.m.morozov@gmail.com> wrote:
Hello.
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.
<extension name="Bind_DTMF_action"> <condition field="destination_number" expression="^DTMF_CALL_CONTROL$"> <action application="bind_digit_action" data="dtmf_call_control,*1,exec:execute_extension,attented_xfer XML ${context},both,self"/>
<action application="bind_digit_action" data="dtmf_call_control,~^\d,exec:execute_extension,send_dgts XML ${context},both,peer"/> <action application="digit_action_set_realm" data="dtmf_call_control"/> </condition> </extension>
<extension name="Send_DTMF"> <condition field="destination_number" expression="^send_dgts$"> <action application="send_dtmf" data="${last_matching_digits}"/> </condition> </extension>
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. The problem is that a lot of popular PBX and call managers (for example Cisco UCM) do not recognize DTMF with such low volume. Is it possible to set this value in freeswitch as we need or this parameter is not configurable? -- WBR Alex M.
