Cisco and T-Mobile Announce Wi-Fi Calling For Business

Cisco Systems, Inc. (NASDAQ:CSCO) and T-Mobile USA have announced the Wi-Fi Calling for Business. This service ensures reliable voice calls over a Wi-Fi connection. The service also ensures seamless roaming of voice and data traffic between cellular networks and Wi-Fi.

This service will help businesses save on communication costs. Cytec Industries is one of the early adopters of the service. About 1,000 out of 6,000 Cytec employees have actively been using the service for the last 6 months.

This service requires a Cisco wireless LAN infrastructure. The infrastructure includes Unified Wireless Network technology and Cisco Compatible Extensions (CCX). Unfortunately CCX currently only works for BlackBerry and Nokia smartphones, but not Android and iPhone yet.
