Embedded Asterisk PBX

Abstract

VoIP is currently at the time of expansion and is still more frequently used technology for real-time communication. Software branch exchange (PBX) based on Asterisk is very popular solution for corporate telephony at this time. Because Asterisk is open-source software, in that case gratis, therefor is his running related only with energy cost. Energy cost in this case is direct proportional for power consumption of hardware where Asterisk PBX is running. Therefor this theses is focused on minimalisation of energy cost needed for Asterisk PBX running with reference to minimal lost of computational power. Also is this project focused on chances of additional network services running also on this PBX, and thus create complex mini-server which is further named as HomeRouter. Specific of this project is emphasization for minimal energy cost related with network services running on specified hardware. This devices are usually named as SOHO (Small Office/Home Office). In last section of this theses is also described howto implement additional network services running on HomeRouter as HTTP, FTP, SMB server, VPN concentrator and so on.
