DTMF between SCCP and SIP phones on same CME

Hi all,

I configured a CME with SCCP phones (6921 and 8941) under TelephonyService and 3py SIP phone under voice register global on CME 9.0 (IOS:

c2900-universalk9-mz.SPA.152-2.T1.bin).

Audio and video calls works successfully betwwen SCCP and SIP phones but I'm not able to send DTMF from SCCP to SIP when SIP phone dial SCCP extension while when SCCP call SIP extension everything is working.

This is my config:
