Hi,

try tcpdump and than export audio to a file so you can play it ( or play it directly in wireshark )
maybe the GSMGW is sending InBand DTMF who knows :=)

also, depending of the GSMGW, used, try to identify what DTMF method is accepting/sending

I also had a similar problem. 
The problem was only on some GSM gateways. And on the incoming call, playanddigits recognizes DTMF normally, and the outgoing one does not. 
It did not work out that way. 
In the console, when dtmf_verbose is enabled, pressing the buttons is visible. In tcpdump it is seen that it is in RFC that a click comes. 
Moved to bind_digit_action. Works without problems on all types of locks and in any directions.

Hi

I need to originate calls to Indian mobile numbers from my python ESL script. I used to use service from a company for sending calls from Freeswitch to GSM network for which I set up external SIP profile. 

But recently I bought my own GOIP hardware, though I am able to make calls but DTMF events are not getting captured on Freeswitch, API like playandGetDigits does not work and there are no logs on Freeswitch console.
