There are three options for connecting the MDA220 to your desk phone.

Desk phone + EHS cable (sold separately)

continue below. If you will be using the Desk Phone + EHS cable, refer to EHS Getting Started
guide that came with your EHS cable or at poly.com/accessories for installation instructions.
Desk Phone (standard)
1 Connect one end of the telephone interface cable to the back of the switcher.
2 Disconnect the handset coil cord from the base of the desk phone and re-connect it to the
telephone interface cable junction box.
3 Connect the remaining end of the telephone interface cable into the open handset port on
the desk phone.
Your desk phone handset will continue to work; it’s just hooked up differently.
