Abstract: There is provided a method for centralized screening of a communication session, comprising: receiving, at a server, a request from a caller client terminal, to establish a communication session with a callee client terminal; analyzing, by the server, the request according to a screening set-of-rules; and transmitting, from the server, a screening response to the caller client terminal according to the analysis, wherein the analyzing and the transmitting are performed by the server independently of at least one of real-time status of the callee client terminal and real-time response instructions from the callee client terminal.

Abstract: There is provided a method performed by a server, comprising: detecting a dropping of a bidirectional voice communication on a communication segment between a first client terminal and the server, the communication segment part of the bidirectional voice communication established between the first client terminal and a second client terminal using respective communication segments with the server, the dropping triggered by insufficient resources for maintaining the bidirectional voice communication in a desired quality for the first client terminal, receiving at least one message from the first client terminal, the at least one message including instructions for restoring the bidirectional voice communication, the at least one message received over available resources sufficient for transmission of the at least one message over the affected communication segment; and restoring the bidirectional voice communication according to the received instructions when sufficient resources are available for maintaining t

Abstract: A method for presenting a title in an audio phone call, comprising: receiving a phone call destination address and a phone call title from an initiating client terminal, the phone call destination address and the phone call title are received via a user interface of the initiating client terminal; initiating a phone call from the initiating client terminal to a receiving client terminal corresponding to the phone call destination address; and sending the phone call title to the receiving client terminal to be presented on the receiving client terminal with an indication of a pending phone call.

Abstract: A system for updating a user interface. The system comprises at least one monitoring module adapted to monitor a plurality of multi-participant voice discussions held in a plurality of voice chat rooms and a processing unit adapted to identify a plurality of current voice discussion features in each of said plurality of multi-participant voice discussions, update a user interface to reflect at least some of said plurality of current voice discussion features of each of at least some of said plurality of multi-participant voice discussions, and instruct the presentation of said user interface by a client terminal of a user.

Abstract: There is provided a method for establishing a communication session between a client device of a caller and a client device of a callee, comprising: iteratively attempting to establish a communication session, via a communication interface of a client device of a caller, to a communication address of a client device of one of a plurality of callees represented as contact members stored in an electronic address-book, wherein each respective iterative attempt includes; detecting failure of the establishment of the communication session; applying a set-of-rules associated with the respective contact member and stored in a set-of-rules repository, to attempt to establish a subsequent communication session via the communication interface; and attempting to establishing further communication sessions defined by a sequence of the set-of-rules when previous attempts at establishing communication sessions have failed; wherein each respective communication session allows human language based communication between the c
