The Akuvox SmartPlus App can receive calls from Akuvox door phones when the devices are connected to the Akuvox SmartPlus Cloud. However, in some old communities, the internet may not be available.

To ensure the SmartPlus App can still receive calls and open doors when the door phone is offline, Akuvox rolled out a call transfer feature.

With this feature set up, the SmartPlus App can receive calls from Akuvox door phones through Akuvox indoor monitors, even when the door phone is offline.
