[Freeswitch-users] DTMF Star Event Inconsistent

I'm calling a registered soft phone (ext. 1003) via the event socket interface. That is, on one side i have some Java code connecting to the Freeswitch event socket interface and placing calls and on the other hand i have the soft phone registered to Freeswitch and awaiting for calls.
Now, when i get a call on the soft phone, i press a sequence of DTMF digits. The sequence of DTMF digits is intended to be read by the Java code via the socket interface. Most things run pretty smoothly: i can place calls, i can send DTMFs, i can receive them on the other hand.
The inconsistent behavior i'm seeing is following. For DTMF-0 to DTMF-9, and DTMF-#, i receive two events via the socket interface. The first one is in CS_EXCHANGE_MEDIA state and the second is in CS_EXECUTE state. Yet for DTMF-* i receive inconsistent number of events: sometimes only one single event in state CS_EXCHANGE_MEDIA sometimes two events as in the case of other DTMF digits.
It seems there is a pattern in this "inconsistency". The odd DTMF-* (first, third, fifth, etc.) generate only one CS_EXCHANGE_MEDIA event while the even (second, fourth, sixth, etc.) generate both events.
Can somebody help me understand what's going on?
