Hi Euan,

Maybe your device is sending in-band DTMF while your software expects RFC-2833.

Try setting:
 <action application="start_dtmf"/>
in the dialplan entry.

cheers,

Hi Euan.
I think you should probably check how your softphone sends DTMF (usually could be in-band, rfc2833 or SIP Info, and you have set FS to work with rfc2833 dtmf).

Hope it helps.

Hello again, kind Freeswitch group.

I am using ESL to control my calls entirely from a Node application.  I am using the 'modesl' package to create an ESL connection and listen to the FS events 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
