Hi, I have some questions about sending outband DTMF tones: 1.) What is the right way to send DTMF tones to a parked call? In my tests "uuid_send_dtmf" seems to work only if I first send something (like a silent WAV file) with "uuid_broadcast". (I'm testing with Yealink SIP phones and X-Lite on my computer) Is this the right way to do it, or should I do something else to "initialize" the connection? 2.) Is there a way to detect if all DTMF tones have been played? It seems to me that "uuid_send_dtmf" returns before all tones have been played and I don't see any Freeswitch event triggered after the DTMF sequence has ended. 3.) Can I make "uuid_send_dtmf" play faster? "uuid_send_dtmf <uuid> 1234@1" plays much slower than for example "uuid_broadcast <uuid> tone_stream://w=100;d=100;1234" probably because of the "Queue digit delay of 40m" after each tone. Can I reduce this delay or is this a limitation of the DTMF outband protocol? Thank you in advance, René
