Jabra Smart Cord 3.5mm (female) to RJ9

The Jabra Smart Cord (specifically the Jabra GN1200 Smart Cord, Part No. 88011-100) is an adapter cable that allows specific headsets (like the Jabra Evolve series with a 3.5mm jack) to connect to desk phones with a standard RJ9 headset port. It features a female 3.5mm input and a male RJ9 output. The cable is designed with eight selectable wiring configurations via a sliding switch to ensure universal compatibility with almost any brand of desk phone (e.g., specific models from Cisco and Avaya) without needing complex technical setup.
