hi:
   my snom 300 problem seems solved.
   i tried a snom 320 with firmware 7.1.8, and found DTMF is ok.
   i upgrade the firmware to 7.1.30 and it is ok too!
   this inspires me.
   why my snom 300 with the same firmware 7.1.30 is broken.
   i re-flash the firmware, it is still broken.
   i do a reset to factory default, and the DTMF is working now!!
   there must be some hidden garbage settings inside when upgrade snom
firmware 
from 6.5 to 7.1.30.
   do a factory reset seems cure the misbehavior for me.
