Abstract
A user terminal may include an IP Multimedia Subsystem, IMS, client to enable the terminal to communicate with an IMS network. The IMS client may include a conference creation and control unit configured to create and control an IMS conference involving one or more participants, participants being identified within a conference INVITE or REFER message by respective Uniform Resource Identifiers, URIs, within a URI list. The conference creation and control unit may include a response handling unit configured to receive from the IMS network, in response to the sending of an INVITE or REFER, a SIP response message including an XML body specifying an Outgoing Communication Barring, OCB, service invocation result and configured to present the specified result to a terminal user. Related methods and application servers are also discussed.
