Folks,

I got two questions:

1) How do i configure Freeswitch to detect inband DTMF?
2) How do i play DTMF to the remote caller?

Appreciate your answers.

Klaus.

I tried the following but for unknown reason, the caller is not getting anything:


JavaSession s = new JavaSession(uuid);
s.answer();
s.streamFile("/usr/local/freeswitch/sounds/1.wav");
s.execute("send_dtmf", "0123456789ABCD*#@2000");
s.hangup();


I can play the file 1.wav without problem but the "send_dtmf" is simply being ignored. I used wireshrack to check if maybe the outbound DTMF was sent and not played by my softphone. But this is not the case.

Any idea?

Thanks,
Klaus.

Might want to try queue_dtmf

Yes, i understand that streamFile blocks. And i indeed want to play the DTMF after the file is streamed. But playing the DTMF doesn't work. I have also tried removing streamFile without better result. Is there maybe a specific mod that is should install to have send_dtmf work?

I also tried the following with javascript, but without sucess:

session.answer();
session.execute("send_dtmf","0123456789ABCD*#@2000");
session.hangup();

Thanks,
Klaus.

HI Brian,

Thanks for your suggestion. I just don't see how this would help me. I understand queue_dtmf is to be used before bridging. But i'm not bridging calls. I'm just originating calls and interacting with the remote device. What i really want is the inverse of getDigits() that you can call anytime in the call to send DTMFs. The Asterisk equivalent to what i need would be SendDTMF.

Any further idea?

Klaus.

Can you make sure you're on the latest code? And try again?

Thanks. Will let you know in half an hour to one hour.

problem is if this is over sip, the dtmf is queued into the rtp stack and sent in real time as the call progresses.
Since you are hanging up right away, it never gets a chance to send it.
you must sleep long enough for the entire tone to be sent.

I added a convicence variable set once you call send_dtmf that will tell you how long to sleep
until all of the digits should be sent.

update to latest trunk and try this:

JavaSession s = new JavaSession(uuid);
s.answer();
s.streamFile("/usr/local/freeswitch/sounds/1.wav");
s.execute("send_dtmf", "0123456789ABCD*#@2000");
s.execute("sleep", s.getVariable("last_dtmf_duration"));
s.hangup();

Thanks Anthony. I was wondering if it would make sense to make this blocking in the same way other methods are (e.g. streamFile). By that i mean that the execute method would actually return not after a computed amount of time but effectively when the last DTMF is sent.

Hi,
I meant to confirm that the fix rocks. I can now send DTMF with the following:

session.answer();
session.execute("send_dtmf","0123456789ABCD*#@200");
session.execute("sleep", session.getVariable("last_dtmf_duration"));
session.hangup();


Thanks to all,

Klaus.
