Analyst unimpressed by fixed-mobile convergence - ZDNet UK

Vestergaard took issue in particular with BT's Fusion service, which routes mobile calls over a firm's wireless LAN and out onto the public telephone network via the company's own telephone exchange, or PBX. The analyst said there were plenty of other ways to route calls out through the PBX without having to use Wi-Fi networks. "I would suggest that you wait for a couple of years for complex [fixed-mobile] installations," Vestergaard said. "There are some clever things you can do with a PBX. It doesn't even have to be IP or hybrid. You can do many of these things with a normal PBX."
