摘要
A system and method for transmitting voice data traffic over a wireless medium, such as a voice call using a wireless Internet Protocol mobile phone on a wireless local area network, to increase the quality and the number of voice calls on a Basic Service Set. Endpoints are capable of dynamically switching to alternate voice coding profiles. The WLAN is surveyed by a wireless endpoint to determine whether a congested network condition exists. Coding profiles may be dynamically switched to decrease the congested conditions and improve call quality. If dynamically switching of profiles in not available then the wireless endpoint gracefully degrades the transmission by periodically dropping packets until network congestion reduces and/or call quality increases.
