## Long description

The StarTech USB-C to RJ9 Adapter (UR9-HEADSET-ADAPTER) provides a direct connection between devices with a USB-C audio-capable port and RJ9 handset or headset jacks on office desk phones. Designed to enable audio routing for calls and unified communications, the adapter allows a computer or compatible USB-C endpoint to send and receive audio through a phone’s handset/headset port without modifying the phone hardware. The compact adapter supports standard telephony headset interfaces and is intended for professional environments where interoperability between modern endpoints and legacy desk phones is required.
Advantages
This adapter offers a straightforward plug-and-play solution for integrating USB-C devices with traditional RJ9 headset/handset ports. It preserves the desk phone’s physical connection while allowing audio from a USB-C device to be used for calls and conferencing. The product’s small form factor and single-cable connection minimize workspace clutter and simplify setup. Compatibility with USB-C audio endpoints removes the need for additional converters or phone alterations.

Office workers using unified communications applications on a laptop or desktop with USB-C audio
Customer support and call center agents who need to use computer audio through existing desk phone headsets

How to use

Once connected, configure the audio input/output settings on the computer or unified communications application to use the USB-C audio device if necessary. The adapter routes audio between the two devices and allows the desk phone headset or handset to carry the computer’s call audio without altering phone wiring.
