A method of determining at least an estimate of media latency for push-to-talk communications includes determining a first time associated with transmitting a first packet from a push-to-talk transceiver device. In a disclosed example, the same device receives a second packet that corresponds to the first packet and includes an indication of the first time, a second time associated with receipt of the first packet by another device such as a push-to-talk server and a third time associated with transmission of the second packet to the push-to-talk transceiver device. That same device determines a fourth time associated with receipt of the second packet. In a disclosed example, the push-to-talk transceiver device uses a relationship between the first time, second time, third time and fourth time for determining at least an estimate of media latency associated with the push-to-talk communication corresponding to the first and second packets. A plurality of latency test procedures are disclosed.
