SOURCE: I can here them but they can't hear me
Hello,
I have the TRU9585 with 4 hansets. We used them for about 3 months, worked great. One day, I can hear caller, caller can't hear me. Problem was a defective transistor in base unit. Part number C2120, small 3 legged device near bottom of unit. Replaced it with generic NPN transistor from Radio Shack. Caution...should only attempt repair if you have worked on electronics before and can solder...Also C2120 configuration is not standard, configured emitter-collector-base instead of emitter-base-collector...Good luck!!!
SOURCE: The other party cannot hear me from one of the Uniden DCX 640 handset
don't hear with uniden 640 dcx

A phone uses a voltage drop to determine when it is answered or hung up. What is happening in your case is the phone or base unit, or worse yet the house wiring has a short to ground somewhere. This also cause the static you hear. You can get a regular phone and plug it into the same cord and see if it works normal. If so it is not the house wiring but the phone or base unit. If so you can only hope to find the short yourself which is very time consuming and difficult on modern digital units. Sorry to say it's cheaper to get a new unit than pay for repair. The only other thing that cause those symptoms is the batteries are going dead. I assumed you checked this first. If not you can try changing the battery pack on the phone.

Check Windows Sound mixer for application volume. Down in system tray at right side of taskbar double click sound icon for XP or click sound icon once and click Mixer for Vista. Look through volume settings for your phone application. Make sure it is not muted and volume is up.
