Hello & Welcome to Just Answer,
Sorry I didn't see your question earlier and to hear of the issue you are having with your phones.
May I ask:1) The Model Number of the MAIN BASE UNIT of the phone system you are working with (the model you sent is for a handset only)?2) How many TOTAL handsets do you have with this system?3) What phone service provider (phone company) you have for this phone line?4) Do you still get a dial tone - when you pick up the handset and press the TALK button?
I see it has been a few days and I just wanted to follow up to see if you have any more questions concerning this issue or if the issue was resolved.
I look forward to any further questions or results that you may have.
Thanks, ***** *****
