Hello Mary & 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 Make & Model Number of the phone system you are working with?
2) What phone service provider (phone company) you have for this phone line?3) If you have ANY other devices (phones, fax, alarm system, etc.) attached to this same phone line (not part of the MAIN system), and if so, are they working properly?
4) WHEN did this issue first begin (or was noticed)?
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 only ask because MOST of the time when I hear symptoms like this (can not receive calls but can make them), it is usually traced back to the service provider's service, and sometimes "goes away" after a short time.
If it does NOT go away, the service provider will have to be contacted to report this issue.
I look forward to any further questions or results that you may have.
Thanks, ***** *****--. .-(im)
