[Freeswitch-users] Lua in-band DTMF

[Zsotya]

Hello All,

I am trying to send audiable in-band DTMF from Lua script.
If I use the session:execute("send_dtmf", 1) command I can see  #1  
arrives to the other party in SIP messages but I cannot hear the DTMF  
audio.

How can I set the type of the DTMF? Can I force from lua or is it a  
gateway or global settings? If I need an audiable DTMF is there any  
better way than play dtmf sounds from wav files?

Thank you!
