If you hope to connect a UCM to 3CX, just don't. Not worth it.

It's easier to move everyone to 3CX.

If you are really adventurous, have a good understanding of SIP, a great deal of patience, and are self hosted, you might be able to do this using a Bridge trunk. However, the use of Bridge trunks are now only supported between 3CX PBXs, so you you'd be on your own.
