UCE shim service
UCE = User Capability Exchange. A shim is basically a compatibility layer for an API, that makes sure anything that uses the API does so correctly.
Used for RCS. Provides a discovery service for users to see the capabilities of other users.
UCE is based on SIP PUBLISH and SIP SUBSCRIBE/NOTIFY.
Devices PUBLISH their capabilities to a presence server, when another device wants to find out what the other party supports, the device sends a SUBSCRIBE to the presence server which then returns a NOTIFY of what the other party supports.
