Does anybody know where I can buy replacement speaker phone microphones for the 550.4400 handset? I have 4 handsets that are useless because the microphone causes a buzzing noise when you call through the intercom or speaker phone.

The part is real easy to replace, if I could just find some. I have tried electronics dealers and cannot find the correct diameter mic.

Thanks for any suggestion you may have.

The problem w\ those was oxidation on the inside of the microphones.

I've found a good smack on a sturdy desk works pretty damn good...

Sledgomatic. Now available at a Graybar near you. :rofl:

Steve,

We have replacement handsets and mics.
