Advanced concept of voice communication server on embedded platform

Abstract

The paper deals with a design of an embedded Voice communication server which was developed within the scope of the BESIP project (Bright Embedded Solution for IP Telephony). The project brings a modular architecture with additional functionality such as a speech quality monitoring and a protection against security threats.The speech quality assessment is carried out in a simplified computational E-model and we implemented our proposal into the BESIP as an optional component. In the security module. We applied a standard approach to the intrusion detection and protection and in addition to the mentioned modules we come up with an idea of unified configuration based on the NETCONF protocol. We implemented ntegrated the complex support of NETCONF configuration protoco into OpenWRT and our modifications were accepted by OpenWRT community. The paper describes the inidvidual modules, their features and entire BESIP concept.
