DTMF problems with SoundStructure Interface Cards

We just recently upgraded from Cisco CallManager 8.6 to Cisco CallManager 11.5  We have 4 Soundstructure interface cards and they are not passing DTMF on calls (ie putting pin in for a conference bridge).


Has anyone else had that issue and if so any suggestions on what to look for either on the Soundstructure's web interface, or the configuration on CUCM.
