Give Avaya desk phones the call-control behavior wireless headset users expect. Jabra LINK 14201-35 provides an electronic hook switch solution for Avaya 1600 and 9600 Series IP phones, allowing users to answer and end calls, adjust volume, mute the microphone, and hear ring tone directly in the headset. For teams that depend on fast call handling, that translates into fewer interruptions and a cleaner desk setup. The adapter supports hidden installation and magnetic ring-tone detection, helping preserve a professional workspace while keeping the connection path out of sight. It also supports Bluetooth 3.0, auto pairing, and music streaming, making it a useful bridge between desk phone environments and wireless headset workflows. This is the kind of accessory that matters in high-volume office and contact center deployments: it removes friction from every call, reduces the need to reach for the handset, and helps users stay focused on the conversation. For organizations standardizing on Jabra wireless headsets with Avaya phones, LINK 14201-35 is the compatibility layer that makes the setup work cleanly and predictably.
