1. A method comprising:
- sending, by utilizing internet protocol communication, a real-time audio data item from a terminal of a sending party to a terminal of at least one receiving party over a communication system, said real-time audio data item comprising a plurality of real-time audio data packets, wherein the sending of the real-time audio data item includes sending of data packets containing real-time audio data information and sending real-time audio data transport packets;
sending, in association with the sending of the real-time audio data item, to the least one receiving party, a request to send an acknowledgment report;
sending, responsive to the request, by utilizing internet protocol communication, an item acknowledgement report from the terminal of each of the at least one receiving party after the end of the real-time audio data item, wherein the item acknowledgement report is sent as embedded signaling within real-time audio data traffic and;
initiating the sending of the real time audio data item by sending a leader packet from the terminal of the sending party to the terminal of the at least one receiving party over the communication system, wherein;
the leader packet contains the request to send the acknowledgement report,the terminal of the sending party sends data packets containing real-time audio data information,the terminal of the at least one receiving party detects the end of the real-time data item, andthe terminal of the at least one receiving party, responsive to receiving the request in the leader packet and detecting the end of the real-time audio data item, sends the acknowledgement report to the terminal of the sending party.

Abstract
The invention relates to communications systems, and especially to real-time data (two-party or multi-party) communication in communications systems. A real-time data item is sent from a sending terminal to a number of receiving terminals over a communication system. In accordance with the present invention, each receiving user terminal acknowledges the reception of the item by sending an item acknowledgement report after the end of the item. The acknowledgement report may be sent after a successful reception of the item, unsuccessful reception of the item or in both cases.

13. A user terminal for communicating real-time data items, the user terminal comprising:
-
(A) for a sending mode of operation; a mechanism that sends, by utilizing internet protocol communication, a leader packet comprising a real-time transport packet to at least one receiving terminal over a communication system in order to initiate the sending of the real-time data item, the leader packet containing the request to send an item acknowledgement report, said real-time data item comprising a plurality of real-time data packets; a mechanism that sends, by utilizing internet protocol communication, real-time transport packets containing real-time data of the real-time data item to the at least one receiving terminal; a mechanism that sends, by utilizing internet protocol communication, a trailer packet in form of a real-time transport packet in order to indicate the end of the real-time data item; a mechanism that receives an acknowledgement report originating from the at least one receiving party by utilizing internet protocol communication; a mechanism that displays item information provided on the basis of the received acknowledgement report, and (B) for a receiving mode of operation; a mechanism that receives, by utilizing internet protocol communication, real-time data packets of a real-time data item from a sending terminal over the communication system; a mechanism that receives, by utilizing internet protocol communication in association with the received real-time data packets of the item, a request to send an item acknowledgement report; a mechanism that detects an end of the item; and a mechanism that sends, responsive to receiving said request and detecting the end of the item, an acknowledgement report by utilizing internet protocol communication.
