Cross platform real-time voice transfer

This article is describing protocol implementation for real-time voice transfer from Windows based Operation system to embedded system based on Linux Open Source OS. There is presented implementation of A-law based algorithm as codec, which is usually used in digital telecommunication signals mostly in Europe. For real-time voice transfer we are used RTP protocol. Presented Solution works both direction but only in half duplex mode. Main applications can be security systems and robotics or mobile robotics solutions with interactive features.
