We have a new setup with DPH-125MS phones. How to we view "Missed Calls" as shown on LCD?
zer0fx:
Use the Call History button on the phone to get the following,
Press Call History Once: Redial
Press Call History Twice: Missed Calls
Press Call History 3 Times: Received Calls
To scroll between the numbers, use the up/down arrow keys.
To exit the menu, click Cancel
Вместо Call History нужно нажимать кнопку Redial на DPH-150S
