Nec elite 48 caller id

SOURCE: caller id not working

the directory key is storage for caller id. dtr80 is not the type of system but the type of phone.
The system needs to have other components like a mif card in order to store caller id.
Also if your phone does not ring with incoming outside call than you will not get caller id.

The call forwarding was turned off. To turn on, press speaker, enter 793, press 1(for set), press extention number, and enter 300. If you have call forwarding on and are looking for more rings, do the above steps except press 2 (for clear).

depends on the type pf system. Do you have a coib installed in the system? Is caller id setup or programmed? If there is no mif card in the switch you cannot save caller id info. It only shows up when the phone rings and while on the call. There should be a directory key that you can price to scroll through the numbers if everything above is correct. ldtsnj.com

Your system needs to have a mif-m card and kmm chip installed and all programming setup in order to scroll through the caller id. If this is all setup you can hit the directory button and than use the arrow buttons under the display to scroll. ldtsnj.com
