SELECTIVELY PATCHING ERASURES IN CIRCUIT-SWITCHED CALLS WHOSE FRAME ERASURE RATE RISES ABOVE A THRESHOLD BY ESTABLISHING AND SYNCHRONIZING A VOIP STREAM

摘要

The disclosure is related to selectively patching frame erasures in a first stream. A receiver receives the first stream, receives a second stream corresponding to the first stream, detects a missing frame in the first stream, and attempts to replace the missing frame in the first stream with a corresponding frame from the second stream.
