Use voice in new ways and new places

With AT&T UC Voice, it’s easier than ever to bring voice and UC features together in new ways and new places. Choose from a variety of AT&T UC Voice bundles to get the mix of features you need, which can include:

Single number reach

In-the-office and out-of-the-office voice worlds have come together. Now, workers can have a single number that rings simultaneously on a desk phone, mobile phone and other client devices. They can decrease “phone tag” with peers, partners and customers by increasing first-time reach.

Unified messaging

How much time do your employees waste checking multiple voicemail systems? Bring them together with unified access to a single voicemail box.

Presence and collaboration

Bring the right people together at the right time. During a voice call, use presence to check the availability of colleagues in real time. Send an instant message to an available resource for a quick answer. For face-to-face communication, extend invitations for an on-demand video conference on a range of endpoints -- from an IP video phone to a desktop or mobile device.

Seamless multi-tasking

With a consolidated view into multiple voice and UC applications, workers can move smoothly between tools and communication modes. Need to escalate an issue? Move from a chat with one person to a collaborative conference with many.

Multi-device access

Since AT&T UC Voice works on a mix of select desktops, laptops, smartphones and tablets, employees can think less about which device to use and more about the task at hand.

Flexible Options for Merging Voice and UC

You may want to use AT&T UC Voice solely for IP telephony features as a first step on your transformation roadmap. Or, you may want to take advantage of a full UC deployment, including a UC client application, such as UC Voice with Cisco Jabber, to bring voice and UC tools together behind a single user interface.

If you want to tap into the rich features of an enterprise-grade voice solution with your existing UC client, we can help you integrate AT&T UC Voice with a range of other popular UC client applications you may already use. Either way, AT&T has a solution for you.

When you choose AT&T for UC and voice services, you can benefit from a highly secure, reliable platform with a consistent feature set and support model for global implementations. We also leverage our vendor ecosystem to bring you the latest developments to continually enhance your UC and telephony capabilities.
