Performance of Various VoIP Vocoders using Wireshark with Asterisk PBX

Abstract

A private branch exchange (PBX) is implemented by an Asterisk software. In conjunction with appropriate telecommunication hardware interfaces and network applications, Asterisk is employed to establish and manage the telephone calls between telecommunication endpoints, like customary telephone sets, destinations on the general public switched telephone network (PSTN), and devices or services on voice over internet Protocol (VoIP) networks. A Vocoder may be a system of coders and encoders that is employed to scaleback the bandwidth over the restricted use of bandwidth necessities and restricted capability channels in real time needs. This paper presents Performance of Various VOIP Vocoders using wireshark with Asterisk PBX.
