A method of determining the speech content of a packet carrying speech encoded data missing from speech segment communicated by in a packetized data stream communicated using at least one VOIP link between a server platform and a client platform, the method comprising at the client platform: receiving a plurality of packets carrying speech encoded data forming said packetized data stream; processing each received packet to determine a unique message segment identifier associated with a speech segment of the received packet; processing each received packet to determine if it contains another unique message segment identifier associated with a previously received packet carrying encoded speech data; determining if the unique message segment identifier for the received packet exists in storage means provided on the client platform, and if not, storing the received packet in association with its unique message segment identifier; processing each received packet to determine a sequence identifier; checking if the sequence identifier is contiguous in sequence with a previously received packet stored locally on said client platform, and if not, determining the speech content of one or more missing packet in the sequence sent by the server platform to the client platform by retrieving a packet from said storage means having the same unique message segment identifier as the missing packet.
