Siemens Openscape Mobileconnect

With the ability to keep workers productive and connected plus the 
potential to reduce carrier charges by 15-40%, Siemen OpenScape
MobileConnect is an FMC (Fixed Mobile Convergence) solution that uses a company’s WLAN to provide voice communications on
mobile devices. It automatically selects the best available network,
ensuring low costs and high communication quality. When a worker’s
device is connected to the corporate WLAN, the MobileConnect client
seamlessly routes calls between the carrier network and the WLAN,
so workers can maintain high-levels of reachability without using
carrier networks. And, whether they’re on-site or off, they can access
network systems and services.
