Instead of building an expensive telephony infrastructure, many hotels are taking advantage of their existing Wi-Fi network — and the fact that most guests have a smartphone – to integrate telephone functionality and hotel services in a mobile application that can run on a guest’s device.

In addition to making calls within the hotel, the Mobile Guest Softphone app lets guests make local phone calls without paying roaming charges, book a table in the hotel restaurant, order a taxi, book a spa treatment or order room service. And if guests want to use multiple devices in the same room? It’s a piece of cake, thanks to automatic registration.
