Purpose This paper aims to examine the design and implementation of an advanced ToIP platform for the interconnection of ToIP operators based on the concept of multilateral peering, with a special focus on the design requirements and implementation. Design/methodology/approach Based on the key design requirements of a ToIP peering platform analysed at the beginning of the document, an open source‐based network architecture is proposed. Subsequently, a detailed explanation of the elements and their functionalities that integrate both core platform and management platform is presented. Findings The paper finds that open source‐based ToIP platforms provide a cheap solution for deploying ToIP services such as ToIP peering. Although not as stable as hardware‐based ToIP platforms, software‐based platforms provide a very scalable high‐performance solution for delivering customised ToIP services. Research limitations/implications The paper studies the implementation of advanced VoIP services such as video telephony and the call termination in public switched telephony network or mobile networks. Originality/value The deployment of an experimental ToIP peering platform in Catalonian will help to the large‐scale adoption of ToIP by both enterprise and residential customers. Furthermore, operators can reduce both capital and operating expenditures if they exchange traffic through the ToIP peering platform, reducing, thus, the cost of ToIP calls to end users.
