V Tech phones and the message waiting indicator
 

Yo

Whenever I get voicemail, the blue light flickers on the base and handset ,

Ok so i checked my voicemail , and the lights is stillflickering after i deleted the inbox. Its annoying me. I am about to take some duct tape and cover thelight.......

Any idea how to make the thing stop flickering???

Put it back in the base for a few seconds and see if that makes it go away.

It will usually go away after a couple of minutes. It doesn't go away right after you have deleted the message from your message system. Give it alittle time.
