Abstract: A computerized method of optimizing audio quality in a voice stream between a sender and a receiver VoIP applications, comprising: defining by the receiver time intervals; determining by the receiver at the end of each time interval whether congestion exists, by calculating (i) one-way-delay and (ii) trend, using double-exponential smoothing; estimating by the receiver a bandwidth available to the sender based on said calculation; sending said estimated bandwidth by the receiver to the sender; and using by the sender said bandwidth estimate as maximum allowed send rate.

Abstract: A method of pushing an ongoing VVo1P call from a first currently participating communication device belonging to an account having an account ID to a second communication device, comprising: sending by the first communication device a ‘transfer call’ message to a signaling service; sending by the signaling service the ‘transfer call’ message to at least one selected second communication device; if the call is not a P2P call, sending by one of the at least one selected second communication devices a ‘connect’ message to a relay server, the message comprising authentication information; sending by the signaling service a “call transferred” message to the first communication device; and continuing the ongoing call with the selected second communication device replacing the first communication device.
