You would need either a call manager or call manager express to configure the phone and connect to the phone line.

check your volume level. (press the volume button) and be sure to save the settings.

Since the 3cx softphone worked well, I don't see why you couldn't configure each as for 3cx and make them work as well.

It sounds like you have enabled Do No Disturb accidently. This can be turned on and off by pressing the DND softkey button along the bottom of the LCD display. You might need to press the 'more' softkey to display all options.

Give me your number, and i'll call you! Solved! =-D

The phone will soon display “Reset key sequence detected”
3) After several lights flash press the following keys in order:
