[Freeswitch-users] Out of band DTMF in Javascript

[Steven Ayre]

TeleTone generates audible tones. That's inband dtmf. That won't give you
anything out of band / rfc2833

Rfc2833 packets simply contain the character (3 # etc) being pressed and
its duration. You need to use session.execute("send_dtmf", "#3#") to
generate those.
