Here is my problem.

About a month ago, I inserted my headset as usual, but when I unplugged it, it does not seem to fully disengage the switch that turns the ear piece/speaker phone speaker back on. So if I don't have the head set plugged in I cant use the phone....people can hear me talking into the phone...but i can't hear them....unless I put the headset back on...then everythig is fine.

If I jiggle around with my headset plug and pull it partially out I get clear sound through the ear speaker. Plus the phone rings etc so I know tht the speakers are is all in the jack.

I have tried applying contact cleaner to the 2.5mm male plug for the head set and hoped to loosen it up...but no solution. Any other ideas....I'd hate to have to open the case for this...
