If you have a Grandstream phone model GXP2124, GXP2130, GXP2140, GXP2160, GXP2200, GXV3240, GXV3275, you’re in luck. There is a Plantronics EHS APD-80 adapter cable available for your phone. Instead of using an old fashion HL10 lifter, you can use the APD-80 EHS cable instead. There are no mechanic device attached to your phone that lifts the telephone receiver up and down, instead your Grandstream phone communicates with the Plantronics wireless headset “electronically” and more efficiently. By pressing a button on the wireless headset, the phone will answer almost instantaneously. Here are some basic setup instructions:
Install the APD-80 using the shown below:
Make sure your Grandstream phone is model GXP2124, GXP2130, GXP2140, GXP2160, GXP2200, GXV3240, GXV3275 or it won’t work. If you have other Grandstream models no on this list, you will need to use HL10 lifter for remote answering.
Make sure your Grandstream phone have a firmware 1.0.4.23 or higher, otherwise it won’t work with the Plantronics APD-80.
Go to your phone’s Menu > Config > Headset Type > select “Plantronics EHS”
If needed, purchase an additional 85638-01 extension cable if the APD-80 doesn’t reach your Grandstream phone.
Change the setting on the Plantronics wireless headset base to:
| Setting | CS500 Series/Savi 700 Series |
| Compatibility | A |
| Speaking Volume | 2 |
| Listening Volume | 3 |
