I'm using HMP 3.0 SU 155 for Windows and have some problems to detect DTMF tones, RFC_2833 mode is selected.

DTMF detection is working bad, it detects about 20% of all tones received. I checked with wiresharck and RTP events for DTMF are receibed, but application does not.

I will apreciate any help to solve this problem, it is critical because I have a system to fix.

Thanks in advance.
