Hello & Welcome to Just Answer,
Sorry to hear of any issue you are having with your phones.
To help you with this issue, may I ask:1) The Model Number of the phone system you are working with? That model should be printed on a sticker on the bottom or back of the main base unit and START with KX-TG (but not have an "A" in it).2) How many TOTAL cordless handsets do you have with this system?3) What phone service provider (phone company) you have for this phone line?4) If you have ANY other devices (phones, fax, alarm system, etc.) attached to this same phone line and if so, are they working properly (and reliably)?
Any site related issue including any deposits must be referred to customer service of the site. You may find them in the "my account" on your side of the system.
Please let me know if you have any more phone related questions in the future.
Best Regards, ***** *****
