What you need to know:
1) Plantronics H-series headsets terminate with a Quick Disconnect (QD) and do not plug directly into your telephone.

Understanding Direct Connect Cables vs. Amplifiers
When using any H-series headset with business phones, a Direct Connect Cable or amplifier is required to plug in between your headset and phone. Using a Direct Connect Cable will save you money versus an amplifier but an amplifier will provide optimum sound quality and volume controls. The Plantronics M22 was designed specifically for those who use VoIP phones and need a little more clarity and consistency and basically overall better audio clarity performance. The amplifier will allow you to connect a single or multiple lines all at once. The Quick Disconnect (QD) feature allows you to connect and disconnect without sacrificing the call or disconnecting with the party on the other end. The M22 comes with a 10 foot length cord which will allow you to have more freedom to move around your office, even with your corded office headset.
