We take mobility to a whole new level! See presence of you colleagues, place calls over your data connection with a built-in soft phone and toggle active calls from your cell phone to your fixed extension and vice versa.
Presence - You are able to view the availability of your colleagues in real time all to reduce communication delays. You will easily see if a person is in a meeting, on vacation or busy handling another call. To make finding colleagues easier, they can be grouped by department.
Integrated softphone - No configuration is required, instantly start making calls with our low fixed prices.
PBX services - Transfer calls to both colleagues and external numbers. You can toggle active calls from you cell phone to your fixed extension and vice versa. As an administrator, you can open and close the PBX directly in the app and listen to your messages in shared voicemail boxes.

All colleagues and contacts are kept updated in the phones built in contact book so you can always see who's calling without the need to add the person to your contact book.
