Patent ID: 8831001

Claim:
A method of Voice over Internet Protocol (VoIP) communication, the method comprising: receiving a data stream comprising a set of VoIP packets; and modifying a Real Time Protocol (RTP) header of at least one of said VoIP packets to modify a jitter buffer delay of said data stream, wherein the method comprises increasing the jitter buffer delay of said data stream by performing: (a) identifying a pair of consecutive packets in the incoming data stream, the pair of consecutive packets having consecutive sequence numbers; (b) increasing a sequence number in an RTP header of at least a latter packet in said pair of consecutive packets, wherein the increasing comprises: non-sequentially increasing the sequence number in the RTP header by a natural number computed based on a target increase in jitter buffer delay of a remote VoIP component to which a modified data stream is to be transmitted; (c) transmitting to the remote VoIP component the modified data stream which comprises one or more packet gaps, to cause the remote VoIP receiver to recognize a packet loss and to remotely generate one or more additional VoIP packets using packet loss concealment.
