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.
To help you with this issue, may I ask:1) Can you VERIFY the Model Number of the phone system you are working with?2) How many TOTAL handsets do you have with this system?3) If more than one handset, do ALL handsets have this same issue?
4) WHEN did this issue first begin?
Please take your time to answer each point but REPLY HERE on this page when you can.
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)
