Question about Uniden Cordless Phone
This hum must be coming from base. possible causes could be depleted circuit board on the base, possible moisture / water damage on the base or base could have fallen hard and had some components on it loosen. Solution on either of the above possible causes would be to perform some kind of service on the base. this involves dis-assembling the base and physically inspecting its components inside for such damage, clean its circuit board and reassemble. If somehow technical, doing this should be easy for you.. otherwise consider using a tech for this.

Follow the troubleshooting tips below;
Disconnect the AC adapter from the back of the Base Unit and re-connect it after 5 minutes.
The power has been interrupted during a call.
Restore power to the Base Unit.
If a power failure has occurred and power will be out for some time, remove the battery from the Handset. This will prevent the battery from completely discharging.Move any metal objects away from the base. Make sure no other device is sharing the same AC power outlet as the cordless phone.
Make sure that the Base Unit antenna is fully extended and vertical.
Move the Handset and/or Base Unit to different locations and try again.
Press the (chan) button (if available on the keypad) to select another channel.
Make sure no other device is sharing the same AC power outlet as the cordless phone.

Your hum problem sounds like a ground loop,There are two different types of ground there is a 'ground' in your devices known as the negative side of the supply.
Try another phone as a test,Contact your provider for a new box, yours may be defective.
Try "grounding" the system: try connecting a thin wire between some metal point on your phone box to the nearest outlet plate-screw or water-pipe.
I don't think this would be risky but standard caveats apply. If you are at all unsure about doing this, find an expert friend or hire someone qualified.
Find your phone junction box in the cellar and tighten the screws where the wires are connected.

Hello! Do you have another telephone that you can plug into the wall outlet that the base is plugged into? If you can I believe you will still hear a hum...When a resistive ground, due to wet cable, is on the tip side of the cable pair that feeds your wall jack a "hum" will occur...Even though you are using digital phones there is still a telephone cable from the base to the wall jack...Open a trouble report and have the cable pair tested by a technician...
