Abstract:
1. A method, comprising: receiving at least one data cell over a packet-switched network from a transmitting network device, the data cell including voice data from multiple call connections multiplexed into the data cell by the transmitting network device; de-multiplexing the data cell to separate the voice data according to the corresponding call connections and to identify information related to multiplexing the voice data into the data cell by the transmitting network device; receiving information associated with an alarm corresponding to one or more call connections over the network, where the alarm indicates a lack of voice traffic in corresponding call connection; estimating a jitter value based, at least in part, on the information related to the multiplexing of the voice data into the data cell and the alarm, the jitter value to predict a delay introduced by the transmitting network device when multiplexing the voice data into the data cell; buffering the de-multiplexed voice data to compensate for a delay associated with the transmission of the voice data over the packet-switched network; and adjusting the delay associated with the transmission of the voice data over the packet-switched network based, at least in part, on the estimated jitter value.
