Voice over Internet Protocol (VoIP) has become a widely used communication media. The increase of internet and number of smartphone users has become important factors that supports the broader use of VoIP technology. While on the other hand the number users of Public Switched Telephone Network (PSTN) is still quite a lot, even in office buildings are usually equipped with a device Private Automatic Branch eXchange (PABX). The purposes of this research is to interconnect VoIP networks and PABX network on IPB computer network and also develop a VoIP client application for Android. In this research the use of Android smartphone is limited on Wi-Fi network. The method used in this study consisted of: study of the network topology of IPB, installation of VoIP server, interconnection between VoIP network and PABX, interconnection VoIP server and server of Lightweight Directory Access Protocol, and development of VoIP client application for smartphones. Communication between VoIP and PABX on the IPB computer network has been established, and a VoIP client application for smartphones has been developed. The values of delay, jitter and packet loss are 43.74 ms, 14.76 ms, and 0.81% respectively and the value of Mean Opinion Score (MOS) is between 4 and 4.3. It can be concluded that the quality of VoIP networks in IPB is good.
