Abstract
Modifications to IP based packet network protocols are examined that would make the network tolerant of bit errors in packet payloads or headers. These modifications are tested with communication quality MELP voice traffic. As measured by a PESQ score, improvements in the perceptual quality of the speech are noted that are maximized when error checking is disabled for the entire packet.
