Systems and methods for detecting a voice call are described. In one aspect, a data stream is identified and analyzed to determine whether the data stream is associated with a single device. The data stream is further analyzed to determine whether it is actively communicating data packets and to identify a data packet size. Bandwidth for the data stream is reserved if the data stream is associated with a single device, is actively sending data packets, and the data packet size is smaller than a threshold value.
