Abstract
A communication network for transporting calls, where a service provision entity adds user identification information to call data of a call being set up by a non-dialable virtual subscription such that the subscriber behind the call being set up by the non-dialable virtual subscription may be identified at the network switching layer. This increases the manageability of the network and provides advantages for call interception.
