Wireless Landline Phone Headset – Plantronics CS540 and HL10 Remote handset lifter

A lot of executives and their secretaries often find themselves attending phone (land-line) calls very frequently and for a long time (especially during conferences). A wireless land-line phone headset allows them to not only work on their computer, during those long conference calls, but also lets them roam around the building freely (to make a coffee for themselves, for example) while talking on their phone. Want more? They can lift the headset to pick-up calls, even when they are away from their desk!

People are used to pairing bluetooth headsets with their cell phones. It works with cell phones because they have bluetooth adapters on their cell phones and the limited range offered by bluetooth is sufficient as the cell phone is expected to be in their pockets. But what about land-line phones? This Plantronics CS540 DECT based wireless headset allows people to make hands-free calls with their land-line phones.

There is a base unit that acts as a charger for this convertible headset model and also connects to the land-line phone handset. The CS540 headset and connection to the land-line phone can be seen in the below embedded Youtube video.

Unlike a cell phone, the handset of a land-line phone needs to be lifted before a call gets connected. This can be done in two ways – Either physically, using HL10 remote handset lifter or electronically, using an electronic hook switch. The electronic hook switch is specific to phone models and is shown in the above video. The HL10 remote handset lifter is common to all phones and its working is shown in the below embedded Youtube video.
