Claim:
1. A method for mitigating a latency differential between a first path and a second path over which a transmitting device and a receiving device communicate, comprising: participating in a training phase, initiated by the transmitting device, to determine the latency differential between the first path and the second path, wherein the training phase commences upon receipt, by the receiving device, of a first packet over the second path and wherein the training phase terminates upon receipt, by the receiving device, of a first Silence Insertion Descriptor (SID) frame over the second path; following termination of the training phase, switching, by the transmitting device, a media stream from the first path to the second path; delaying, by the transmitting device, transmission of packets from the media stream along the second path by a time interval, wherein a magnitude of the time interval depends on the latency differential; and preventing, by the transmitting device, an introduction of a media artifact when switching the media stream from the first path to the second path by the delaying of the transmission of the packets along the second path by the time interval.
