Section 1: Wireless Headset Solution for Polycom Phones

Plantronics CS545-XD Wireless Headset:

With a headset, you instantly become more productive being able to write and type without holding or cradling a handset  (Not to mention the reduction in neck and shoulder pain).  With a wireless headset, you take productivity up another notch being able to roam your office while talking.  Ever need to grab a file in another office or ask a co-worker a question?  You can with a wireless headset.  With the CS545-XD you get a light weight, great sounding headset that comes with everything you need.

How does it work?  With the CS545-XD, you will start inbound and outbound calls at your phone.  Most newer Polycom phones have a headset button on the phone.  When a call comes in or you want to make a call, you simply press the headset ‘ON’ button and press your phones headset button.  You are now talking with your caller and free to roam up to 350 feet.  To answer/hang-up calls away from your desk you will need the optional HL10 or EHS cable shown below.

• The CS545-XD comes from our most popular wireless headset series
• Enjoy all day comfort with a lightweight headset (21 grams)
• 2 batteries included for unlimited talk-time
• Includes Over-the-Ear and Over-the-Head wearing options

Optional Plantronics HL10 or EHS Cables for Remote Answering:

Need to answer remotely?  If you want the most out of your headset investment, you will want the ability to answer/hang-up away from your desk.  This increases your productivity again by not missing calls to voice mail or needing to run back to your desk with every ring.  Most Polycom Phones allow remote answering with an HL10 or Electronic Hookswitch  (EHS) cable connected to your wireless headset.   Consult Section 3 below to determine which device is compatible with your specific model of Polycom phone and Section 7 explains Handset Lifters and EHS cables in detail.  The HL10 & EHS cables accomplish the same function, thus you use one or the other.

NOTE 1: The Extension Arm (Part # 76141-01) is an item required for a few Polycom phones to hold the handset in position if you are using wireless headsets with an HL10 handset lifter.









**  Polycom Phones IP320/321 & IP330/331 have a 2.5mm headset jack.  You may need an additional adapter from Polycom (Part Number 2200-11095-002):





If using newer CS-series Wireless Headsets (CS510, CS520, CS530, CS540):
The 2.5mm headset port connector requires Polycom adapter 2200-11095-002.

If using older CS-series Wireless Headsets (CS50, CS55, CS70N, CS351N, CS361N, CS510S):
Alternatively use Plantronics adapter 78333-01.
When using 78333-01 bypass the EHS cable audio connection.
Connect 78333-01 directly between CS base and phone headset connector.

If using H-series corded headsets with Polaris Cable 27190-01:
The 2.5mm headset port connector requires Polycom adapter 2200-11095-002.


NOTE 2: Polycom VVX 500 phone can use Focus, Edge UC, Voyager UC, etc and USB headsets with USB having some restrictions.
               1: Blackwire 300 and Blackwire 500 are not recommended with Polycom VVX series phones. Using the headset can cause mute failure and phone reboots
               2: Mute works local to the headset. Mute sync works with mute icon on the desk phone screen. Mute sync is inconsistent with the mute button on the phone.
               3: Phone firmware must be 5.4.2 to use Voyager Focus.


Section 4: Understanding a Corded Polycom Headset Solution

To have a corded commercial grade Polycom headset solution you will need two items; the headset and either an amplifier or a direct-connect cable.  Headsets, amplifiers and direct connect cable all join together using a quick-disconnect connection.


Quick Disconnect

The first thing to understand about commercial grade Polycom headsets is the headset cable terminates in what the industry calls a “quick-disconnect” connection.  This connection allows you to leave your headset on at all times and quickly disconnect from the amplifier or direct connect cable when you need to walk away from your desk.


Amplifiers and Direct Connect Cables

To connect your headset to your Polycom telephone, you also need an amplifier or direct connect cable, depending on the model of your Polycom phone.  You can view your options in our Polycom Headset compatibility chart located on this page.   As you can see on the amplifier and cable, they terminate on one end with a modular clip, which will plug into your Polycom phone.  

Originally, an amplifier was required for most Polycom telephones when using headsets.  Polycom worked closely with Plantronics to engineer many of their phones to have the amplifier built into the Polycom telephone.  This eliminated the use of an amplifier and allowed a less expensive direct connect cable to be used with standard H-series headsets.  The only negative to using a direct connect cable is you lose your ability to control your outgoing voice volume.  An amplifier gives complete volume control for your speaker and microphone.

Section 5: How Corded Headsets Work with Your Polycom Telephone

When using a corded headset on Polycom telephones, most Polycom phones will use a headset and amplifier or direct-connect cable.


Typical Setup Using Amplifier:

If using any H-Series headset and amplifier, the amplifier will plug into the handset port on your phone.  You will need to remove your handset for each call.  When finished with the call you will return the handset to its cradle to hang-up the call.  If you have a headset port, the standard amplifier is not compatible and will only work through the handset port.  You will have a wide variety of headsets to choose from including noise-canceling models for a loud environment and voice-tube models for a quieter environment.

Typical Setup Using Direct-Connect Cable:

If using a compatible Polycom phone with a headset port, most likely you can use any H-series headset with a Polycom Direct-Connect cable.  The cable will plug into your headset port and you will simply press a ringing line to answer and the ‘headset button’ to disconnect the call.  The advantage of using a Direct-Connect cable versus an amplifier is cost.  The cable will be $28.50 versus $72 for an amplifier.  The disadvantage of using a Direct-Connect cable is it only works on compatible phones (See our compatibility chart above) and you can’t control your out-going voice volume.  If you’re soft-spoken, your caller will have a hard time hearing you.

Section 6: CS500 & W700 Wireless Headsets Available for Polycom Phones


You have a wide range of wireless headsets to choose from for your Polycom phone.  You can choose between different styles and functionality.  A commercial grade wireless headset solution is purchased as a complete system (Base/Charger, Headset, A/C Power Adapter are included).  Optionally a Handset Lifter or Electronic Hookswitch Cable (EHS) will need to be purchased to answer and hang up calls remotely.  The base/charger controls compatibility, microphone volume, speaker volume, and also acts as the charger when your headset is not in use.  There are LED lights on the base to indicate power, charging and other features.

Section 7: Remote Answer and Hang-up For Wireless Headsets

Wireless units give you freedom, and adding a Handset Lifter or EHS cable allows greater productivity by allowing you to answer and hang up remotely.  Both will sense when your phone is ringing and generate beeps in your headset to alert you of a call.  If you choose to take the call, simply press the Call Control Button on your headset to answer the call.  Your phone answers the ringing line and you begin talking.  When finished you press the Call Control Button again to disconnect the call.  You will need to return to your phone to press the appropriate buttons to dial, transfer a call, or to perform any other phone functions.  Most phones will support the Handset Lifter which raises and lowers your telephone’s handset, simulating you answering a call.  The EHS electronically establishes calls on newer phones without the mechanical motor and physical movement of your handset, but otherwise accomplishes the same thing.  Having the ability to answer remotely greatly increases your productivity.  You can answer away from your desk and carry on conversations wherever you need to take them.  It also allows you to answer calls that would have normally gone to voice mail.  This saves you a tremendous amount of time playing phone tag with customers or co-workers.

Section 8: Special Headset Programming for Polycom Phones


Most Polycom phones will need the headset port activated for EHS use, giving you remote answer/hangup capabilities.

1) Make sure the EHS cable is NOT plugged into your Polycom phone
2) From your phone select: Menu-> Settings-> Basic-> Preferences->Headset-> Analog Headset Mode or Electronic Hook Switch Mode
3) Scroll Down to Plantronics Mode, and then press Select – Press Menu to return to the idle display
4) Now that the port is activated, you may plug the EHS cable into your phone and headset base.
We have also implemented the following on a few Polycom VVX phones for corded headsets to function correctly:

To enable Headset Memory Mode:  

1. Select Settings from Home view, and select Basic > Preferences > Headset > Headset Memory.

2. From the Headset Memory Mode screen, select Enabled.

3. Press .

4. To activate Headset Memory Mode, press  twice. The Headset key will flash to indicate that the phone is in Headset Memory Mode.

If your phone has different options, your firmware may have been modified/updated.  This is common with some cloud hosting companies.  Consult your phones manual or contact your phones IT department for assistance.
