If you have Unity Connection w/ Unified Messaging to Office 365, you need to update to 15SU4 to maintain functionality. MS is killing EWS in favor of GraphAPI starting in Oct 2026 with a full shutdown in 2027. #CiscoUC #UnityConnection #Office365
It's official, Cisco NFVIS hypervisor for UC is now available! Now you can ditch VMware before they jack up your rates even more. The SKU is A-NFVIS-COLLAB. It is only supported on BE6k/7k M5/M6/M7 hardware and UC 15SU4/4a software. #CiscoUC #cucm #nfvis
CUCM 15SU4a released Feb 24 to fix the critical defect that deferred SU4. There is also a COP file for those who happened to upgrade to SU4 before the release was deferred. #CiscoUC #CallManager
Certificate EKU changes require audit and replacement of CA certs with client+server Extended Key Usage. Cisco will release updates between now and May 2026 to remove the EKU check when uploading certificates to CUCM, IMP, CUC, CER, CUBE, and Expressways. #CiscoUC #CUCM
Well shoot. CUCM 15SU4 deferred due to a critical defect that crashes the CallManager process.
