Outbound DTMF Issue

We are experiencing a problem with DTMF tones on external attendants.  We have a CCM 4.2 cluster connected to a CUCM 8.6.1 via a QSIG ICT. 

CCM 4.2 <--> ICT <--> CUCM 8.6 <--> CUBE <--> SIP

DTMF works OK from phones in the CUCM 8.6 cluster.  All inbound DTMF works all the way through to the CCM 4.2 cluster.  However, DTMF from phones in the CCM 4.2 cluster does not work.  It was working OK last week when some changes (adding CUC integration) were made.  I have tried reversing most of the changes, but cant get it working again.

Any ideas or TS steps recommended?  Thanks!
