"BT has expanded its BT Onevoice converged voice platform, in a bid to drive the adoption of communications applications to the desktop in large businesses. The company has launched SIP trunking in a number of countries, which it claims will deliver a migration path to unified communications," writes ComputerWeekly.com's Cliff Saran.
"SIP trunking provides connectivity between domestic country voice services and BT's Onevoice global VPN to help customers deploy converged applications.
