UX Firmware and Lync Cumulative Update Compatibility
It’s also worth noting that NET/Sonus maintain a VX and UX Lync 2010 Cumulative Update Qualification Chart that outlines which version of UX firmware is qualified to interoperate with each Lync 2010 Cumulative Update.
If you have UX gateways deployed, it’s probably best that you delay upgrading to this version of UX firmware and Cumulative Update 7 until they are both qualified to work with each other.
