Hello & Welcome to Just Answer,
Sorry I didn't see your question earlier and to hear of any issue you are having with your phones.
To help you with this issue, may I ask:
1) The Make & Model Number of the phone system you are working with? That should be printed on the bottom or back of the MAIN BASE UNIT of the system.
2) How many TOTAL handsets do you have with this system?
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, ***** *****--. .-(im)
