This review analyses Asterisk implementation, performance, and security as an open-source VoIP platform. Eight provided sources were selected: one technical book and seven empirical studies. Data were extracted into a matrix and synthesised into implementation, Quality of Service, VPN security, and research limitations. Asterisk was deployed on Linux servers, FreePBX or Trixbox distributions, OpenWRT routers, powerline networks, wired and wireless environments, and processing clusters. Performance was assessed mainly through delay, jitter, packet loss, throughput, and Mean Opinion Score. Controlled small networks generally produced acceptable quality, while restricted bandwidth, UDP load, unstable media, and inconsistent configurations reduced performance. VPN improved confidentiality, but its impact on QoS varied across studies. Firmware cloning succeeded on identical routers and failed across different devices. Future studies should use current Asterisk versions, modern security protocols, larger call loads, multiple codecs, and standardised test procedures.
