Section 1: Wireless Headset Solution for Grandstream 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 Grandstream 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.

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 Grandstream 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 Grandstream 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.

Section 4: Understanding a Corded Grandstream Headset Solution

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


Quick Disconnect

The first thing to understand about commercial-grade Grandstream 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 Grandstream telephone, you need an amplifier or direct-connect cable, depending on the model of your Grandstream phone.  As you can see in the amplifier and cable pictures, they terminate on one end with a modular clip, which will plug into your Grandstream phone.

Grandstream worked closely with Plantronics to engineer many of their phones to have the amplifier built into the Grandstream telephone.  This eliminated the need for an amplifier and allowed a less expensive direct-connect cable or 3.5mm cable to be used with standard H-series headsets.  The only negative to using a direct connect cable or 3.5mm cable is you lose your ability to control your outgoing voice volume.  An amplifier gives complete volume control for your speaker and microphone.

If you feel the need for more control over your outgoing voice volume, you can opt for an amplifier.

Section 5: How Corded Headsets Work with Your Grandstream Telephone

When using a corded headset on Grandstream telephones, most phones will use a headset with an amplifier or direct connect cable.  Grandstream has worked closely with Plantronics and designed their newer phones with the amplifier built into the phone, so only a direct-connect cable or 3.5mm cable is needed with a headset.


Typical Setup Using Amplifier:

If using any H-series headset and amplifier, the amplifier will plug into the headset port on your phone.  When you initiate a call, you simply press the headset button on your phone.  When finished with the call you will press the headset button again on your phone to end the call.  You will have a wide variety of headsets to choose from including noise-canceling models for use in a loud environment and voice-tube models for a quieter environment.

Typical Setup Using Direct-Connect Cable:

If using a Grandstream phone with a headset port, you can most likely use any H-series headset with a Grandstream compatible Direct-Connect cable (See our compatibility chart).  The cable will plug into your headset port, and you 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, and you can’t control your out-going voice volume.  If you’re soft spoken, your caller will have a hard time hearing you.

For the Direct-Connect cable: Plantronics U10P-S Cable


Typical Setup Using 3.5mm Cable with Grandstream Phones:

Grandstream also uses a 3.5mm jack for headset use on a select number of phones, which includes the Grandstream GVX series.  The standard 40845-01 3.5mm to quick-disconnect cable is approximately 6 1/4 inches long.


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

In an earlier section, you learned Plantronics wireless headsets are compatible with Grandstream phones.  To get into more details, you have two families of wireless headsets from which to choose.

The CS500 series is the standard version of wireless headset that connects to your Grandstream phone.  This series works well if your only mode of communicating within the office is through your Grandstream phone.  You have four basic models from which to choose with different wearing styles.  All-day comfort and great battery life will get you through the busiest of work days.

The Savi W700 series of Plantronics headsets not only connects to your Grandstream phone, but also to your PC and Bluetooth phone.  This allows you to keep one headset charged and ready for use no matter which way someone tries to contact you.  This is a great convenience, combining three headsets into one.  If you need to join a webinar or listen to online training, you simply press the PC button on the base, and your headset becomes your audio device for your PC instead of blasting the office with your external speakers.  The Savi  headset is also there for use with your mobile phone while in the office (you cannot use the headset with your mobile phone outside of the range of the base).  The Savi headset wearing style choices are the same as for the CS500 series.  The base is what’s upgraded to support two other communication points (PC & Mobile Phone).

With both solutions you can also gain remote answer/hang-up capabilities with an optional HL10 or EHS cable.

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 calls remotely.  Both will sense when your phone is ringing and will generate beeps in your headset to alert you to an incoming 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 can begin talking.  When finished, just 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 your answering a call.  The EHS cable electronically establishes calls on newer phones without the mechanical motor and physical movement of a handset lifter, 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 Grandstream Phones

TECH TIP #1: Microphone Volume Setting

We have experienced headset microphones being extremely sensitive on initial installation where your caller hears nothing but feedback and echoing.  To solve this issue, follow these steps:

1) Connect the computer to the same network as the phone
2) Access your phones firmware (from your computer) by logging into it’s specific IP address
3) Make sure the phone is turned on and shows it’s IP address.  You may check the IP address on the LCD or go to MENU ->Status->Network Status
4) Open a Web browser on your computer
5) Enter the phones IP address in the address bar of the browser
6) Enter the administrators login and password to access the Web Configuration Menu
    There are two default passwords for the login page:
    End User Level – Password= “123”
    Administrator Level – Password= “admin”
7) Locate the audio control panel
8) Select headset TX (transmit) gain
9) You will have 3 choices.  -6, 6 ,0
10) Select the next lowest number (default is typically 0) until your caller can hear you comfortably.
When changing settings, always SUBMIT them by pressing the “Save” or “Save and Apply” button.  After submitting the changes, reboot the phone for them to take effect.


TECH TIP #2: Remote Answering with EHS Cables

We have also experienced EHS cables initially not answering remotely, and you need to be at your phone to press the headset button to establish a call.  To resolve this issue:

1) Unplug the EHS cable from the wireless base and telephone.

2) Unplug the power cord from the base and wait 60 seconds.

3) Plug the power cord back into the base and wait for the power indicator lights to come on.

4) Plug the EHS cable into the wireless base and telephone.

That should resolve the issue, and it is now ready for use.


TECH TIP #3: Remote Answering with EHS Cables

EHS Phone Programming:
The GXP1760/GXP1780/GPX1782/GXP2130/GXP2140/GXP2160 supports normal RJ11 headset and Plantronics EHS headset.
To use Plantronics EHS headset:
Go to the GXP1760/GXP1780/GPX1782/GXP2130/GXP2140/GXP2160 web graphical User Interface (GUI) or Network Setting Site by using your phones IP address:
Settings->Audio Control: Headset Type. Select “Plantronics EHS” and reboot the phone to take effect.
Settings -> preferences -> audio control and selecting “Plantronics EHS Headset” as opposed to the default “normal” and reboot the phone to take effect.
