Zultys is a software solution for businesses to provide a mobile workforce with a unified communications platform that allows them to communicate with their business customers, vendors, and partners. Zultys is compatible with both Android and Apple iOS mobile operating systems.

With Zultys, companies can provide a single number to all of their mobile users, regardless of whether they are working from home, on the road, or from a mobile device. This allows companies to monitor the presence status of all of their mobile users, regardless of whether they are in the office, on vacation, or on sick leave.

The mobile app enables employees to receive and make calls to the company's central voice mail box. Users can send and receive IM messages with their contacts, which allows employees to communicate with the contacts right from their device. Users can also receive alerts and notification messages right from the mobile app. 

Zultys also provides advanced call handling and transfer functionality. Users can hold calls, transfer calls to another user, or send a message to the caller. Users can also add contacts to their address book so they can be quickly contacted via phone or email.
