The Phonum hands-free phone is the ideal solution for mobile conferences over the internet, whether in the office or at home. It primarily operates via Bluetooth with a PC, laptop, or smartphone. Additionally, Phonum features a USB port as a secondary interface, allowing the device to be used even with poor wireless connections.

With Phonum, small conferences, including video or teleconferences with participants at remote locations, are possible. In the office or conference room, the maximum number of participants is 8 people.

Phonum is powered by a lithium-ion battery, which is charged via the USB port. If necessary, the device can also be operated via USB, with the battery charging in parallel to its use.

Operation is done through capacitive touch sensors, allowing the user to answer or end calls, adjust the volume, select the microphone characteristics, and mute or activate the microphone.
