“…Something to consider is to choose a computing platform that provides sufficient CPU and memory resources to handle the desired calling load. IP PBX are also highly customizable in both hardware and software; by using Application Programming Interfaces (APIs), one can easily interface external applications with an IP PBX; on the hardware side, it can support traditional analog/digital extensions through FXS, FXO or E1/T1 cards interfaced through a PCI-E slot [12].…”

IP-PBX have grown considerably in the telecoms and IT industries in recent times due to their low cost, high customizability, open source and hardware-independent nature. Unlike traditional PBX systems that are TDM-based and require a separate wired infrastructure to operate, an IP PBX can be attached to the local LAN and uses SIP with RTP over Internet Protocol (IP) for signaling and data transport, respectively. Asterisk-based IP PBX has become a de facto standard for open-source low-to-medium calling capacity requirements. Single Board Computers (SBCs) are attracting considerable attention from academics, hobbyists and the industry, due to their compact size, low cost, low power, portability and fair processing ability. Raspberry Pi series SBCs are the pioneer in the field, having Pi, Pi2, Pi3 and Pi Zero in production, supporting different processing and storage capabilities. An IP PBX embedded on the raspberry Pi SBC can serve an adequate number of users and provide a tiny platform that can fit in a pocket and be transported anywhere while preserving the functionality of a complete IP PBX. Such systems can be phenomenally successful in situations where large infrastructures cannot be taken, for instance, in warzones or disaster-affected areas where communication networks are damaged, necessitating an immediate requirement for an ad hoc-based communication system. In this paper, we aim to explore the performance of an Asterisk®-based IP PBX installed on a Raspberry Pi 3 (model B) platform in terms of concurrent call handling using different codecs.
