Hello again, kind Freeswitch group. I am using ESL to control my calls entirely from a Node application. I am using the 'modesl <https://github.com/englercj/node-esl>' package to create an ESL connection and listen to the FS events <https://freeswitch.org/confluence/display/FREESWITCH/Event+List> and then answer a call if the number matches a dialplan I want to control using the mod_command "uuid_answer." I have gotten as far as attempting to recognise DTMF events, but I am getting no DTMF events through. So, I tested my Freeswitch installation using the IVR demo, and it looks like DTMF is not being received by Freeswitch at all. I monitored fs_cli and I can see that the demo is just waiting for digits, even though I can hear them being pressed in my softphone. Is there any particular modules that I need to ensure are installed, or configuration I need to make in order to enable DTMF? In a previous email to this list, I saw a message advising to set the following in sofia.conf. <param name="dtmf-type" value="rfc2833"/> I can see that the property is loaded inside sip_profiles > internal.xml But changing this has had no effect. I still do not get any DTMF events being recognised in fs_cli Many thanks for any help or advice you can provide. Kind regards, Euan
