In this paper we present the results of an experimental analysis of the behavior and performance of VoIP calls using different codecs in a wireless mesh network (WMN) based on the IEEE 802.11g standard. Most measurements were done during the rainy season in a Brazilian Amazon region.We assessed the call quality of codecs using real measurement conditions showing the codecs coding performance over wireless mesh networks.Both between unidirectional and bidirectional transmissions were studied.
