Why buy an expensive headset just for your Aastra office phone? Use the Headset Buddy Adapter and your existing 2.5mm phone headset with Aastra office phones that have a handset or headset jack. A big productivity enhancer for home businesses, call centers, sales people, or anyone who is on the phone all the time, but doesn't want to buy two headsets, one for a 2.5mm phone, and one for your Aastra office phone.
