Abstract:
Voice over IP telephony, allowed by large band and low cost communication through Internet, is the base of a project of a communication platform for IP-PBX. The new idea is to use open source software to implement an IP phone switch system by a business LAN, where a virtual PBX can provide services and reliable communication. The challenge is to virtualize many systems in one physical system using Linux vservers resources. This approach yields many advantages: easy restore from crash events, security and simple resource management. The drawback is a heavier hardware load, solvable using more powerful CPU and memory architectures.
