Abstract: A method of controlling a user interface to display participants of a call in dependence upon the participants' speech activity in the call, the method including monitoring the speech activity of the participants in the call and determining whether a participant is an active participant or an inactive participant in dependence on the participants' speech activity over a minimum time period of the call. In response to determining whether a participant is an active or inactive participant, an active participant is displayed in a first area of the user interface and an inactive participant is displayed in a second area of the user interface. The first area of the user interface is larger than the second area of the user interface.

Abstract: Provided is a method, computer program product, and apparatus for estimating the quality of a call in which a first user terminal will comprise an end point. The method comprises establishing an end-to-end connection between a first user terminal and a node, which end-to-end connection is via an access point of a network by which the first user terminal is connected to the network; displaying information indicative of an expected quality of a call in which the first user terminal will comprise an end point, in dependence on information indicative of the quality of the end-to-end connection; and providing call initiation means for enabling a user to then selectively establish a call between the first user terminal and a callee. Also provided is a method, computer program product, and apparatus for estimating the quality of a call between a first user terminal and a potential callee.

Abstract: Communication systems and methods for providing premium multiparty communication sessions between a plurality of callers. The plurality of callers may comprise an initiating caller who initiates the premium multiparty communication session but who does not have a status in the communication system which is recognized by an operator of the communication system for allowing the premium multiparty communication session to proceed; and a premium multiparty caller who has a status in the communication system which is recognized by the operator of the communication system such that the operator allows the premium multiparty communication session to proceed, wherein the premium multiparty caller is a different caller to the initiating caller. The premium multiparty caller funding the premium multiparty communication session may be transferred and assigned during communication sessions.
