However, as different codecs perform differently well under certain network conditions like delay, jitter or packet loss, this can lead to a reduction of quality if those conditions change during the call. This paper makes two core contributions: First, we compare the speech quality of a set of stan- dard VoIP codecs given different network conditions. Second, we propose an adaptive end-to-end based codec switching scheme that fully conforms to the SIP standard. Our evaluation with a real-world prototype based on Linphone shows that our codec switching scheme adapts well to changing network conditions, improving overall speech quality. crawler fileadmin/papers/2012/2012-aktas-new2an-codecswitching.pdf Online LNCS Proceedings of the 12th International Conference on Next Generation Wired/Wireless Networking (NEW2AN 2012), St. Pettersburg, Russia.
