Hi,

Check that you are not in Silent Mode. (Silent Mode On should be displayed on the screen of each handset).

Here is how to enter / exit Silent Mode

1. With the phone in standby, press and hold # on any handset. The phone prompts you to select the number of hours (1 -9 or Always On) that you want it to stay in silent mode.

2.To confirm, press # or just wait about 5 seconds. The phone turns on the answering system and displays Silent Mode On on each handset.

3.After the selected number of hours, the phone automatically exits silent mode.

To exit silent mode manually, press and hold # again.
