A method and apparatus for routing voice packets through a communications network wherein the routing priority of the packets is based on a location of a packet within a sequence of transmitted voice packets, relative to one or more identified voice packets in the transmitted sequence. In one embodiment of the invention, the routing priority of a voice packet is based on the location of the packet in a sequence of packets relative to voice activity, such as the beginning, middle or end of a talk spurt. For example, the routing priority of the first several voice packets of a talk spurt is increased to compensate for the fact that there is less network jitter protection available at the receiver for these packets. In another embodiment, the routing priority of a voice packet may depend upon its location relative to a cellular handoff from one transmitter to another.
