Hi Anthony, Let me add some few facts. 1) I am sending DTMF using RFC2833 and the IVR is using Inband 2) The problem is not limited to when i send DTMF. It also happens when i try to play a file. 3) The functions are from my java code. They send commands to Freeswitch via socket interface. 4) The same functions are working perfectly when the remote IVR sends DTMF via RFC2833. 5) I have a pause of 2000 ms after sending the DTMF. Let me reformulate my problem. I have a spurious dtmf-# being detected by freeswitch where nothing was sent by the other party. The strange thing to me is that Wireschark (running on the same machine as Freeswitch) detects the proper digit sequence. Klaus. -------- Original-Nachricht --------

is the send dtmf inband as well? did you try doing a pause after send dtmf to give it time to deliver it? I still don't quite get what you are saying because i don't recognize the functions in your example.
for good measure i added 2 new commands to FS
the flush_dtmf application you can execute before playing the file
and the uuid_flush_dtmf api command you can send to an arbitrary uuid maybe try those

HI,
I'm attaching the console log and event-socket traffic. In the latter case, i gathered only the last few Digits (including the spurious one).
I also have the wireshark trace that i can send you off the list if you wish.
We ran the same IVR (VoiceXML App) with a platform that supports RFC2833 i didn't have this problem. With this platform we unfortunately don't have this feature available.

gather a console log at debug level and a trace of the event_socket traffic.

Hi Folks,
It's me again with a DTMF issue. Here is what's going on. I have a remote IVR and i'm writing some code to communicate with it, exercise it, and test it. The remote IVR is playing DTMF as inband.
Right now, Freeswitch can detect all DTMF digits from the IVR. The interaction between my code and the IVR is essentially a combination of playing files and sending and reading DTMFs.
The issue: whenever my code plays a file or send a DTMF digit, the following attempt to read DTMF fails. By failing i mean that there will be a spurious DTMF detected by Freeswitch that was not sent by the IVR.
That is, if i have something like:
sendDTMF("3"); getDigits("38373", "#"); // # is the termination character
After executing the sendDTMF, getDigits fails because it immediately detects a pound. Yet this pound is not sent by the IVR. I can check this by having wireshark running both on the IVR's computer and on Freeswitch's computer.
Any idea what may be causing this problem? Is there some sort of Echo going on or something like that?
Thanks, Klaus.
