Hi,

but in order to receive DTMF-Events you need to issue start_dtmf first:

You can use start_dtmf in a dialplan to enable in-band DTMF detection (i.e. the detection of DTMF tones on a channel). You should do this when you want to be able to identify DTMF tones on a channel that doesn't otherwise support another signaling method (like RFC2833 or INFO).

After start_dtmf is executed FreeSWITCH will detect DTMF an generate events for them so you can read the DTMF-Digit via ESL.

Hey Daniel,

Thanks for your response. 

I don't want to specify commands in dialplan, i want to give commands to Freeswitch from my Perl script over ESL.
I want to get DTMF input.
I tried "READ" command but that needs sound file, but i want plain DTMF input without playing any sound file.

Thanks & Regards,

Hey

I want to get DTMF digits over ESL. I got function "uuid_recv_dtmf" in freeswitch api document, but i am not getting how to retrieve data from this function.
Can someone guide me about API command or function of get DTMF?
