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