---------------------------------------------------------------------- 
this is a major problem if you are connectet to a Cisco SDP
(Indband->rcf2388) as it send DTMF that can be as low as "1"

RTP Event, DTMF *, Event Duration 1
RTP Event, DTMF *, Event Duration 41
RTP Event, DTMF *, Event Duration 81
RTP Event, DTMF *, Event Duration 240 END
RTP Event, DTMF *, Event Duration 240 END
RTP Event, DTMF *, Event Duration 240 END

acording the the rfc any DTMF that has a duration that is less than 40ms
must be ignored, but asterisk will react to any rfc2388 packets it resive
