I have been working on issue 13996 [1] that provides support for most of
that.

There is an additional, unreleased patch that supports receiving an out
of dialog REFER's for iDivert support as well.

Access to the unified endpoints is not a problem. Lack of access to, or
packet captures from a full CUCM installation is. 

I was able to get required SIP+XML for DND and CFwdALL from a CME
instance but not BLF ringing indication or server side conferencing.

CME only appears to support a sub-set of the SIP endpoint's features.
