  1. Carma F (verified owner)

    These only work if you have a handset lifter. They do not work with a headset button.

    • Wayne Baumgartner

      TECH TIP: If you leave the headset on all the time and don’t use an EHS cable or lifter, the busy light will always remain on. If you turn your headset on/off between calls, or use and EHS cable or lifter, the busy light will turn on when talking and off when you hangup calls.

  2. The blue lighted part catches the eye so that I’m not interrupted on the phone.

    I love that it is obvious right away when I am on the phone.

  4. JC

    Great product and the order was filled and shipped quickly and correctly. Great company to do business with.

  5. Sharon

    I had only utilized Avaya before, and these work great.

  6. Kate

    This has been most helpful in our busy office because I’ve got the Busy Light place on top of my monitor using the mounting strips enclosed, and it helps people know when I’m on a call, especially when using my headset 🙂

  7. Help Desk

    We ordered one of this product to test for our help desk personnel to tell when they were in the midst of a call. It has helped cut down on distractions and therefore improved customer service. When we ordered enough to have one for all of our personnel they were out of stock but arrived quickly, and we were kept informed during the entire process. Great Experience!

  8. ACE

    So cool & let’s co-workers know that I’m on the phone & also has a futuristic vibe.

  9. GM Parts center

    We added the busy light in our phone room and it has helped tremendously with the confusion of who’s one the phone. Would definitely do it again.

    Smaller than expected, which was nice. But this device does not work as expected or as described for a soft-phone (PC connection). It just flashes blue all the time whether I am on an active call or not, which is contrary to the PC LED indicator on my Savi W720 base which goes from green to red. So the base station has the ability, seems to be something with this product. Also there are no install instructions in the box or online, and the base station instructions do not mention such a device. There is only one possible port to plug it into, but I chatted for support to confirm. Would be nice if they just clarify that connection.
