I did run some test to reproduce the problem. I'm using Version 1.0.pre4 (8797:8820M).

The call is originate through openzap. Event_Socket trace: http://pastebin.freeswitch.org/4677 Result: There's no problem. The DTMF handle correctly. I'm receiving all the DTMF in the right order without any duplication. Test 2 ----------------------------------------------------------------- Enter this set of DTMF (123456789012345678901234567890*) while the playback command is active. The call is originate through openzap. Event_Socket trace: http://pastebin.freeswitch.org/4678 Result: There's a problem. The DTMF don't seem to be handles correctly. I'm not receiving the DTMF in the right order, because there's some duplication in the DTMF and I even miss some DTMF.
