Improving Network Performance of IP PBX Based Telecommunication System

Abstract

IP-PBX based communication has become a human need in the era of technology. Some researchers design a wireless telecommunication system based on IP PBX using Raspberry Pi. The previous researches have small network coverage and problematic on the ability of the system to support multiple concurrent connections. Based on these problems, these research aims are to expand the coverage area and increase the number of concurrent calls. This study used Asterisk FreePBX for the media configuration of the servers. The clients: laptops and smartphone devices used Linkin and Bria softphone. The testing was conducted in terms of voice and video services in the form of signal strength, CPU performance of servers, and network performance parameters such as delay, jitter, and packet loss. The results obtained that the CPU performance of the servers for seven calls simultaneously is around 16.9% compared with previous research, at an average of 45%. Based on ETSI standards, the measurement of network performance parameters when communicating between clients outperform than previous research. The clients can communicate well up to 390 meters.

Analisis Perbandingan Performas IP-PBX (Internet Protocol Private Branch Exchange) Berbasis Cloud dan Physical Server Menggunakan Protocol SIP (Session Initation Protocol) Studi Kasus PT. Link Net, Tbk

“…IP-PBX (Internet Protocol Private Branch Exchange) merupakan sistem telepon berbasis IP yang digunakan untuk menghubungkan kantor atau cabang dalam sebuah organisasi atau perusahaan [10]. IP-PBX merupakan evolusi dari sistem telepon tradisional yang memanfaatkan jalur analog atau TDM (Time Division Multiplexing) dan memungkinkan pengguna untuk melakukan panggilan suara dan video melalui jaringan internet [1].…”

Design a Real-time Communication System using 3CX Software-based Private Branch Exchange Phone System on Raspberry Pi Device

“…Before the data packet reaches its destination, it may encounter some disruptions. Thus, network performance metrics such as throughput, latency, jitter, and packet loss should be monitored to determine the network's quality [13] [9] [22]. The International Telecommunication Union-Telecommunication (ITU-T) G.114 recommended standard for network performance is shown in Table 1.…”

Analysis Of Voice Quality on Aircraft Telephone Through Internet Telephony Gateway in Voice Over Internet Protocol

“…This is because VoIP can be assigned to any Ethernet and IP address, unlike traditional telephones which have to have their own ports in the Central or PBX. When planning a VoIP network [3], it is necessary to have a server that functions as an IP PBX [4].…”
