Secured mVoIP Service over Cloud and Container-Based Improvement

The VoIP technology is being revisited to support diversified services and mobile computing has been changing to mobile cloud computing paradigm. In this paper, we design and implement cloud-leveraged secured voice services, enabled by the combination of open-source software PBX (private branch exchange), shared hardware platform, and mobile devices. We also test and verify the end-to-end delay of the secured voice communication. In addition, we propose a preliminary idea to improve the portability by adopting Docker-based containers.
