Abstract:
1. A method comprising: receiving at a receiver a voice signal in the form of a sequence of data packets; using an automatic level control component of the receiver to detect that one of the received packets is a silence packet or a noise packet; receiving at a jitter delay control circuit from the automatic level control component a signal or signals to indicate that the one of the received packets is a silence or a noise packet; determining whether dropping of the one of the received packets is urgently needed, wherein the determining includes whether a pre-determined period has timed out without the dropping of the one of the received packets since the one of the received packets was determined that dropping the one of the received packets was necessary; and dropping the one of the received packets in response to the signal or signals received from the automatic level control component; wherein said automatic level control component includes a gain adjustment block and a level estimation and active voice detector block, said gain adjustment block controlled by the level estimation and active voice detector block to adjust a gain applied by the gain adjustment block to an audio signal, said level estimation and active voice detector block of said automatic level control component being used to detect that one of the received packets is a silence packet or a noise packet.
