An end user can invite other end users into their UDN. The receiving end user must have the Cisco UDN mobile application to view the invitation which can be declined or accepted. If the user accepts the invitation, the guest end user can select the device among the ones registered to be part of the host's UDN. The Cisco UDN application provides visibility to the user's devices as well as the guest's invitation status, and the guest devices in the UDN. The guest can reclaim or delete the shared device from the host’s UDN. The host also has an option to delete the guest. Also, if a user receives an invite and does not accept the invite, the invite expires automatically after 30 mins.
