Methods and apparatus are disclosed for synchronizing a local clock in a Voice over Packet Network. In an example method, a data packet is transmitted from a transmitting device with an associated transmission frame rate determined by a remote clock signal, and is received at a receiving device. The receiving device stores the received data packet in a jitter buffer and generates a local clock signal. The data packet is retrieved from the buffer at an associated retrieval frame rate determined by the local clock signal, and an error indicative of the difference between the transmission frame rate and the retrieval frame rate is generated. The retrieval frame rate is then adjusted in accordance with the determined error.
