Hello & Welcome to Just Answer,
I'm Greg and will do my best to assist with this issue today.
Sorry to hear of any issue you are having with your phones.
To help you with this issue, may I ask:
1) The FULL Model Number of the phone system you are working with? If this is a cordless system, that model should be printed on a sticker on the bottom or back of the MAIN base station (model sent is for a cordless handset).
2) Can you CONFIRM that when the handset is MOVED CLOSER to the MAIN BASE it starts to function properly?
3) Have the batteries in ANY of the handsets been replaced recently - or EVER?
Please REPLY using the box below and the SEND button.
