I have bumped something on my NEC DTU 16D-2 phone - the feature light is blinking and cannot be contacted by other colleages but can answer incoming calls.

how do I use your answer ?

we are using nec ip2ap-12txd tel2(wh), incoming voice is very low can u suggest how to increase the volume

Press Feature and then 1. This will turn on the MIC.

Depends on what blinking light it is, but try feature and the button. If its the red led at the top of the phone, it is a voicemail. Could also be DND, try feature, 69, feature.

Try Feature 69 then feature. The phone might be set to DND

Press Feature + 69 + Feature to cancel DND.

Feature + 60 + Feature turns DND on.

Jennifer209, if you press FEATURE + the button VM is pre-programmed on what does it display? It should show the extension number pilot to VM. If you call it directly, what happens? If you get no answer calling it directly, your VM may be down.

Kaait, is it getting into the VM that's the problem, or doing things inside the mailbox that is the problem?

This is a phone system phone and each station you want to ring when a certain phone line rings has to be programmed into the system. This is not something you can change at the phone itself. You will either need to pay a company to make programming changes or locate a programming and installation manual for your phone system (not the phone) and try to re-program it yourself. If you have not done this before it will not be easy but it may be worth the effort so you can continue to make your own changes instead of paying someone $200 per hour to do it for you.

 

There is also the remote possibility your phone's ringer is broken. You can try swapping your phone with another of the same type and model to see if it will ring.

hi,1.to adjust the ring tone volume. from your phone set,press speaker dial 601.press the arrow key up or down to adjust. 2. if your station is programmed as system admin phone,then you can press feature 80 feature.to toggle between day or night.do not press speaker button while doing this. 3.the headset port need to be program,or you can do without it,by purchasing the headset came with the adapter and connect thru the handset cord. the new model is DTH-16D.
