Greetings,

I also use a headset at work from the same company (Plantronics), If the battery is faulty it will not power and you can't use it.

The wiring has gone bad. Try re-connecting all wires.

Good Luck from Headsets Direct!

You will need the Plantronics HL10 handset lifter in order to have the CS55 ring, indicating an incoming call. The HL10 also allows you to answer remotely on most phones and hang-up remotely.

Echo is usually caused by the transmit (speak) level on the unit being set too high.

1. First, try lowering the volume of the telephone. If you still hear an echo, adjust the volume of the headset itself.

2. The master transmit controls of the headset are the ABCD switch settings on the bottom of the base. A is the lowest and D is the highest setting.

3. You can fine tune this setting with the plus (+) and minus (-) buttons on the back of the charging base.

4. If this doesn't fix the echo, try moving the configuration dial on the left side of the charging base. The recommended setting for most phones is 1.

Had similar issue.

This how I fixed it
1) set bottom mic to A
2) set dial on the side of CS55 to "Setting 1" most typical
3) set sound lever on the back to "1"
4) played with mic control on the back until quality became sufficient

If the Plantronics CS55 wireless headset shows that it is on, you have to make sure of the following things.

a. the green LED on the base turns on when you turn the call switch on from the headset.
b. the small green LED on the side of the headset is blinking.
c. the telephone headset is lifted from the cradle.
d. if the headset is not charging and the Amber light on the base does not blink when you place wireless headset on it; trying placing the headset more firmly.
e. If the headset is not charging and the Amber light on the base does not blink even after placing the wireless headset firmly on the charging cradle, you may need to change the battery.

Alternately you can try resetting the Plantronics CS55 wireless headset.

Reset Plantronics CS50, CS60 or CS55 Wireless Headset

If you have problems with the sound or connection of your Plantronics CS50, CS60 or CS55 wireless phone headset, you may want to try to hard reset it using the following steps:

Note: Ensure the IntelliStand switch (on the right side of the charging base) is in the - position and NOT the = position.

1. Press both the call control button and the listening volume/mute button for 5 seconds. When the indicator light blinks release both buttons.

2. Press the call control button again. The talk indicator light will again blink to indicate the headset is back to normal.

3. Disconnect the AC charger from the AC charging jack for 5 seconds.

4. Reconnect the AC charger.

Now give the Plantronics headset a try.

James, plug the phone cord that comes out of the back of the CS55 base into the handset port of the Cisco phone, not the headset port.  Then plug the coily cord from the cisco receiver into the front of the CS55.  Don't use the "Headset" button on your Cisco phone, just lift the receiver off.
