==Voice VPN==

A Voice VPN [1http://www.voice-vpn.com/index_files/VoiceVPN.htm] combines Voice over IP and [[Virtual Private Network]] [[VPN]] technologies to offer a method for delivering voice services between site PBXs [[Private branch exchange]].

The site-based [[Voice Router]] acts as an intelligent voice switch which creams off the interesting calls and routes them over the corporate data network e.g. IP-VPN. As the voice calls are now carried over the data network then all inter-site calls now cost zero cost per minute – as you may know this could be a significant saving potential for most companies.

In addition long distance calls can also be routed over the Voice VPN [http://www.voice-vpn.com/index_files/VoiceVPN.htm]to an appropriate destination site [[Voice Router]] e.g. if the UK company calls a US-based customer then calls are re-routed over the Voice VPN to the US-sited [[Voice Router]] before exiting to the US PSTNɸ[[PSTN]]ɸ. Therefore call rates become local in-country rates rather than international rates.
