Hi Ahmed,

Can u try changing the cord connecting Handset and Base of the phonewith another working phone?

you need to try these permutations to reachthe conclusion.

Hi Ahmed,

In a FIX...

Raise the RMA for a phone.

Hi Guys,

If someone have this fault, Solution: First confirm that the magnet does exists in the cradle where the handset sits. If it does then then It is the reed switch magnet sensor inside the phone. Either it is becoming lazy or needs replacement. Get a magnet and pass it several times over the keypad (Voice mail LED) near where you place the handset and listen to the switch inside clicking. Then give it a try by placing the handset on hook and off hook to see if it works. You may notice a slight delay in taking action.
