Step Into the Future of Communication with Avaya Vantage K155
A Smart Desk Device That Does More Than Just Ring
In today’s fast-paced, hybrid-first business world, traditional desk phones just don’t disconnect it anymore. Employees want the flexibility to collaborate from anywhere, IT teams need simplicity and security, and organizations are looking for tools that do more without the clutter. That’s where the Avaya Vantage K155 comes in—an Android-powered, all-in-one smart desktop device that redefines the desk phone experience.
Whether you’re in a corporate office, a hospital reception, a university classroom, or managing a team from home, the Avaya K155 transforms how you connect, collaborate, and communicate.
More Than a Desk Phone—It’s a Communication Powerhouse
Forget the basic call-and-hold features of yesterday’s phones. The K155 is built for the future, offering a native UC (Unified Communications) experience right out of the box. With built-in HD video conferencing, calendar sync, instant messaging, and one-touch access to meetings, it lets you run your day from one screen—effortlessly.
Equipped with a 5-inch touchscreen and mechanical dial pad, it strikes the perfect balance between modern usability and familiar functionality. It’s ideal for users who still want a tactile dialler but don’t want to give up the speed and convenience of a smart device.
Hear Every Word. See Every Detail.
From executive boardrooms to noisy retail floors, clarity matters. The Avaya Vantage K155 delivers enterprise-grade audio powered by four built-in microphones with noise reduction for crystal-clear voice transmission. Whether you’re using a Bluetooth headset, speakerphone, or the handset, your conversations sound sharp and professional.
Do you need to be on a video call? The integrated 2MP camera delivers smooth 1080p video with a digital shutter for privacy control. And thanks to HDMI support, you can even extend your meeting view to a larger screen, ideal for group discussions or presentations.
Built for Any Industry, Perfect for Every Role
From hospitality to healthcare, retail to education, and corporate enterprises to the public sector, the K155 fits right into your existing ecosystem. Its customizable interface and support for third-party Android apps mean you can integrate it into virtually any workflow.
Seamless Connectivity for a Smarter Workflow
The K155 isn’t just powerful—it’s versatile. With a wide array of ports and connectivity options including Bluetooth, Wi-Fi, USB-C, NFC, RJ45 Ethernet, and HDMI, you can customize your setup to fit any workspace.
Pair your cordless handset, sync your calendar, plug in a mouse and keyboard, or connect to external monitors. The K155 supports:
- USB flash drives (up to 32GB)
- Wired and wireless headsets
- Multi-port USB hubs
- Android device charging
Whether you prefer a desk stand or wall mount, with or without a handset, this device adapts to how and where you work.
