Ia5849 manual lost manual..."message waiting" keeps flashing, have cleared all messages

I had the same issue on my RCA 25255re2 and worked with customer service at RCA. They had me hold down the delete button for 5 seconds, release the delete button, then press delete one more time. That cleared the phantom L1 message waiting issue we were having at my office

Does your phone service provide you with a voicemail box? If so, you likely have a message waiting for you on your voicemail inbox.

need a make and model to help here

The term we used for this back when I worked for the phone company was a "stuck message waiting indicator" and the way to fix it was:

Call yourself and leave a message.
Hang up and wait 2 minutes (we used to say 5 minutes, but 2 is plenty)
Retreive/delete your voice mail message
Hang up and wait 2 minutes


That should clear the blinking light.

Press down the "find handset" button until the paging beep stops (about 5 seconds) and this will reset the indicator lights on the handsets.

Slide the Nortel Grey Bar above the Hold & Rls buttons to reveal the setup button.

1. Hit that button to show *Options List / # Setup list
2. Press * to go into options.
3. Use the arrow buttons or hit 3 to go into CLEAR MESSAGE WAITING
4. Then hit 3 again to clear the message waiting

This should resolve the blinking light.

go to the phone where the light is flashing press intercom #409. you may have to do that more than once. Keep doing it until the light goes out.
If the phone system is a DK 8 orDk16 press intercom 409 this will cancel the message waiting light that could have been cativated by a different extension.

Have you tried the telco message waiting clear?
