Wireless Mesh Networking is envisioned as a solution for next networks generation and a key technology for supporting VoIP application. VoIP has become a killer application and is gradually being tested over emerging areas like Wireless mesh networks. There are various challenges for VoIP in WMN. This Paper discusses E-Model which is the most reliable method for evaluating quality of voice recommended by the International Telecommunication Union-Telecommunication. The paper assesses quality of voice in form of Mean Opinion Score and R-Score in Wireless Mesh Scenario. The Paper gives a review of various codec´s used in voice transmission. This paper also analyzes affect of variation of number of mesh routers over transmission of voice signal in wireless mesh scenario.
