Today we will discuss how to setup a NEC desk phone for a corded headset. NEC deskNEC Phone Systems Dallas & Fort Worth | IP & Digital Phone Telephones phones are headset ready as they have a dedicated headset port for a corded headset, but unfortunately they are not fully “Headset ready” as by default they don’t have a dedicated headset key and must of the time people gets confused and frustrated as their brand new headsets don’t broadcast a phone call. As you can see on the top of your NEC desk phone you have a few available soft keys, these keys are usually free and can be customized on hundred ways. You can always use them for fast dials, extensions and more! We will use one of those in order to have a dedicated headset key that would allow you to use corded headsets as the Jabra Biz 2300 QD Mono Direct Connect Headset.
