The Yealink EHS62 Wireless Headset Adapter (1308120) links a compatible wireless headset system with a desk phone’s EHS interface, so you can manage calls from the headset. Supported call actions include answering and ending calls and adjusting the volume.
The retailer lists Yealink WH64, WH65 and WH68 DECT headsets as compatible. The user guide describes connecting a WH64 base to EHS ports on Mitel, Unify, Avaya, Grandstream, Yealink, Cisco and Poly phones. Some phones require EHS to be enabled in their settings before use.
The listed package contents are the adapter, five interface cables for the named phone brands and a user guide. The cables provide connection options for desk phones from those manufacturers.
