Cisco iP phones are very popular, widely used and are excellent products. A lot of people who use Cisco iP phones also need a wireless headset to answer calls when away from their desk. This normally causes customers to have questions about which headset will work with their Cisco iP phone that allows for remote call answering/ending.

This blog is also intended to provide you with specific models of headsets based on your wearing preference and the exact device you need to order for remote call answering based on your model of Cisco iP phone.

If being hands free, wire free and able to answer and end calls when away from your desk is what you want, the Discover brand of wireless headsets will do a great job for you. You can use the headset alone or you can add an EHS (Electronic Hookswitch Cable), model D625 for enabling the remote call answering feature which allows you to answer and end calls when away from your desk.

Discover D625 Electronic Hookswitch Cables

An EHS cable plugs into the wireless headset charging base and also to your Cisco iP phone to the headset port and the Aux port. Once installed and configured, this cable provides an incoming call alert beep tone into the headset earpiece. This tells you that you have an incoming call and if you press the call control button (on/off button) found on your earpiece, the call is dispatched directly to your headset. We’re always asked the question “how far away from my desk can I go and still be able to take a call?” That question is hard to answer because it depends on a couple of things.

  1. The range provided by your headset – distance varies by brand and model.
  2. The amount and type of obstructions between the headset charging base and your headset. Brick and concrete walls are different from, say, sheet rocked walls. An elevator shaft in between you and your desk can really reduce the signal strength as well. The more obstructions and dense material, the weaker the signal which has a lowering effect on wireless talk range.

Every brand is different when it comes to wireless talk range. In the case of a Discover D901 (mono) or Discover D902 (duo), it’s rated at an industry leading wireless talk range of up to 1200 feet. ¬†Other brands typically provide a wireless talk range up to 350 feet.

The EHS cable needed for the Cisco 7800 series, 7900 series and the 8800 series is the Discover D625. More information on this cable can be found here.

Some might be familiar with a device called a Handset Lifter. This provides the same functionality as an EHS cable, but in a mechanical way by “lifting” the handset receiver from the cradle. Though effective, an EHS cable is superior because it provides the same end result but without the need for adhering peripheral devices to your phone and no future adjustments or tinkering needed as is the case with a Lifter. The price for a Lifter and EHS cable are the same as well. As you can see by the graphic below, a lifter attaches to your phone where an EHS cable simply plugs into the phone and be kept out of sight.
