Voice Over Internet Protocol (VoIP)

Voice Over Internet Protocol (VoIP) is a new category of technology that enables people to make telephone calls via the Internet. Voice signals are converted to packets of data, which are transmitted over data networks (like CommunityNet or the Internet), hence avoiding the long distance charges of the traditional, public-switched telephone network.

Over the next five to ten years, VoIP will likely replace traditional voice telephone systems like Centrex and local PBX systems. Gartner estimates approximately 90 per cent of all new corporate phone systems will be VoIP enabled by 2008.

VoIP holds a number of potential advantages over traditional telephone systems:

• Simplified infrastructure - With VoIP on your network you no longer need separate cabling for your telephone system;
• Scalability - Traditional PBX based phone systems come in many size ranges and it may be necessary, periodically, to scrap existing systems and replace hardware - this is not the case with VoIP systems;
• Reduction in operating costs - Because a VoIP exchange is based on software rather than hardware, it is easier to alter and maintain;
• Reduction in long distance charges - calls within the government network are routed via CommunityNet without traditional long distance charges;
• Improved productivity - VoIP treats voice as if it were any other kind of data, so users can attach documents to voice messages or participate in virtual meetings using shared data and videoconferencing.
• Flexibility - CommunityNet provides the capability of setting up a fully functioning office at any government location.

The ITO is currently working with other government agencies, including Saskatchewan Government Services, on implementing VoIP technology within executive government ministries by March 2010.
