ABSTRACT:
A method to indicate delays in a push-to-talk over cellular (PoC) group call may include offsetting a timestamp in a data stream being transmitted to a late listener to indicate a delay from when the data stream was transmitted to a first listener. The data stream includes data convertible to speech. The method may also include transmitting the data stream including the offset timestamp to the late listener.
