How to license a Softphone

[PoloGeorge]

What is required to license a Softphone on CUCM v12?

Is a Enhanced UCL (Cisco User Connect Licensing) enough?

I've looked at a few post's but I'm unclear if a IPC (Cisco IP Communicator) is also required or anything else?

Many thanks

Ip communicator will consume enhanced license.
