The phone line has a silencer - NorStar Meridian M7310 Phone

You will probably have to call your phone provider and request the number be blocked, that's the only surfire way.

Depends on how it was programmed... Multiple call group phantom or no dialing digits... Take it off frim immediate ring

PRESS PROGRAM #* STORE

set OFF the ringer VOLUME. However you must follow the instr. manual from your Uniden Cordless Phone.
God bless you

Hi! Most phones have a double function for the "#" key. Press and hold this button "#" and the Silence Mode will turn off/on.
I hope this will help you! Have a nice day!
*please don't forget to rate my services :)

Now that's an oldie :-) I have the instructions squirreled away right here

Here's how to program line ringing:

• go to the voice terminal whose line ringing you want to program

• slide T/P switch toward you

• touch a line button (note red lights)

• touch the button again until correct code appears:

RED ON = Ring

RED FLASH = Delayed Ring

RED OFF = No Ring

• repeat this procedure for each line

• return T/P switch to center position.

To activate Silence All:
Press and hold the volume key (on the side of your phone) down in standby mode.While holding the phone this can be accidentally be pushed & set.
(The screen will display "Silence All.")
To deactivate Silence All:
Press the volume key (on the side of your phone) up repeatedly to select a desired volume level.

It sounds like you have the wires hooked up wrong. Check both ends of the wire.

From ext. 10 or 11, press Feature 00, left intercom (twice), right intercom (once), Dial ext. number of boss' phone. Lights on the line button will indicate ringing state for that line:
Green light - Immediate ring
Fast Flutter Green light - No ring
Slow Flashing Green light - Delayed ring
Press each line key until Fast Flutter Green light appears.
Press Feature 00 to exit programming.

Your Handset has been programmed i guess by mistake to be in the same ring group as the main receptionist for C0-01 . Use Google for programming manual to make changes.
