Max UC Desktop and Mobile


Your working life moves constantly from desk to laptop to smart phone to tablet. Now you can use all the features of UltraLine UC from almost any device whether at your desk, at home or on the move.

MaX UC, Fidelity Communications' app for mobile and desktop, keeps you connected wherever you are. It's a fully featured soft phone that enables you to send and receive calls, instant messages (IM), or video calls from any Internet connected device.

Powerful "presence" capabilities allow you to see the real-time status of coworkers - available, offline, on the phone, or in a meeting. This integrates with Outlook so that click-to-dial and IM can be integrated easily into email, as well as CRM applications and business productivity tools.

MaX UC is fully integrated into our advanced IP voice services network and provides reliable performance and great support. Your sensitive information is safeguarded with our industry standard security and privacy measures.

When team members are able to work from anywhere, MaX UC becomes an important part of your business continuity strategy, too.
