The document discusses a project by the Province of Namur in Belgium to modernize the telephone system for its administration. It describes replacing aging PBX systems with an innovative open source unified communications architecture using Asterisk and OpenSER. The AWT, an agency of the Belgian Walloon Government, provided expertise to help the province write technical specifications for the project. The new system will provide IP telephony, voicemail, conferencing, presence and more across the province's 8 sites using open standards-based technologies.
