How to stop the visual ringer blinking

That might be the Voice Mail Warning Indicator.
On the D3098 and similar handsets, it is reset by:

1. press [menu]
2. scroll down to "Global Setup", press [select]
3. scroll down to "VMWI Reset", press [select]
4. scroll down from "No" to "Yes", press [select]
5. handset will chirp, blinking lamp goes out,
6. press [END]

Other models, check your manual. The model number
is on a small sticker under the battery in the handset --

At an educated guess sounds like dial tone is set to decadic if there are two phones the other phone will set off ringer when numbers dialed. May need to get phone provider to change dial mode in exchange line interface circuit to be Dual tone Multi Frequency Dialing and then switch phones to Tone dialing rather than pulse dialing.

You can silence the ringers on the base and handsets at the same time. It doesn't affect the visual ringer on the phone in standby, press and hold Silent on the base. The phone automatically turns on the answering system and shows Do Not Disturb in the display on handset. (The answering system answers any incoming calls without playing anything through the speaker.)To cancel, press Silent again. If you turn the answering system off while Silent Mode is on, the phone turns off Silent Mode.

Is the visual ringer or the message light? If it's the message light then you have unheard messages on the voicemail system provided by your telephone company. This system records messages when someone calls while you're already on the phone. Please contact your telephone company for instructions on accessing their voicemail system.

UNIDEN MODEL EZX290 HANDSET>>>VISUAL RINGET AT TOP (YELLOW LED) FLASHES. HOW DO I TURN THT OFF?

T7316 Manual

The volume control adjusts the handset, hands free, headset, and ringer volume. Someone may have fiddled with the buttons and turned the ringer down enough that it doesn't sound when a call is incoming.

Message/Ringer Lamp: The Message/
Ringer lamp informs you visually that you
have a message or a call.
When you receive a call, the lamp
flashes depending on the ringing pattern.
When the ringing pattern is set to Single
(Slow flash), Double (Moderate flash), or
Triple (Rapid flash) in your PBX, the lamp
flashes. When the other ringing patterns
are set in your PBX, the lamp may not
flash. (e.g., S-Double, Call Waiting
Tone1).
When someone has left you a message,
the lamp is lit continuously.

Please note that the above indicates that ring patterns are set in the the PBX. These are issues that require a real person to sit at the main system and program the features that users need. I hope you have an I.T. person that knows your phone system. If you don't, you'll have to find a communications company in your area that can program your system. Thanks for using Fixya.
