CUBE15.1.3, DTMF conversion between KPML and RFC2833

Hi,

I have CUBE15.1.3 and configured dial-peer,

-to/from CUCM, "dtmf-relay sip-kpml rtp-nte"

-to/from ITSP, "dtmf-relay rtp-nte"

-CUCM SIP Trunk for CUBE=OOB and RFC2833

I have couple UC applications attached to CUCM8.5 which supporting KPML and RFC2833 depends on the application type, works okay the DTMF mechanism without MTP anchor which means no DTMF mismatch issue on CUCM.

My concern is, as per PDI help desk, Cisco developer confirmed that CUBE is not supporting the DTMF conversion between KPML and RFC2833, nor road-map. I tested the DTMF conversion feature with the above configuration of CUBE and CUCM in the LAB without any problem (no MTP anchor) but wonder why its not supporting model on CUBE.

Advise please,
