When publisher goes down, unable to recognize DTMF for the UCCX calls

I had to shutdown my publisher server and Primary Subscriber for UCS move to different DC. Due to this CUBE media resource got unregistered and it impacted UCCX  customer calls. The system was unable to recognize DTMF. The provider uses  RFC 2833 In a band and UCCX use Out of band, due to mismatch in DTMF you need MTP resource.


Provider -  RFC 2833 In band
UCCX Support only -  Out of band

I have changed following and media resource got registered back to CUCM and UCCX issue got fixed.
