Four interfaces support different needs. The diagrams show when a direct connection works and when a base, adapter or bottom cable is required.
The computer recognizes the headset as an audio device for permanent workstations, softphones, CRM and UC.
Validate: USB-A or USB-C port, microphone and speaker selection, mute and volume.
Wireless connection to a laptop or smartphone. Available features depend on the model, adapter and application.
Validate: Voice profile, selected device, source switching and recovery from sleep.
The headset connects to a DECT base, and the base connects to the working device.
Validate: Base interface, power, audio path and a supported EHS cable when remote answering is required.
A quick-disconnect interface separates the headset from the bottom cable for computer or phone use.
Validate: CONTACT CAB4 USB or CAB7 USB for computers; a model-specific cable and pinout for desk phones.
The CONTACT headset remains with the user while the bottom cable is selected for the working device. This simplifies servicing and preserves a familiar fit.
Connector shape alone does not guarantee compatibility. Validate the exact phone model, pinout and electrical characteristics before rollout.
