Abstract
A wireless LAN can be used to support audio communication sessions between wireless communication devices and wired communication devices both configured to operate according to the Internet Protocol. Both the wired and wireless communication devices generate and transmit frames of voice information over the LAN to each other and in the process of generating these frames they place a timestamp in each frame that is used by a receiving communications device to determine when the frame should be played in relationship to all of the other frames of voice information it receives. At times these communication devices can place incorrect timestamp values in the frames of audio information which can affect the quality of the communication experience for a user. I propose to correct any incorrect timestamp values by first recognizing that a timestamp value is incorrect and then rounding the value to the nearest frame boundary.
