Review CUCM traces and confirm CUCM does send the DTMF, if it does, then you'll have to review how to get your quescom to forward the DTMF CUCM is sending.

Try to get it to work, using a SIP trunk, check if you either need to use inband RFC2833 DTMF  or Sip-notify DTMF.  make and inbound call into your quescom and see which one it is using, and set up your cucm accordingly.
