Incoming call :001 on display and can't clear 1

[dawg2]

The system is a TDA 50 and I received a message from my client this morning that Incoming Call : 001, and I can't clear it. I have tried resetting the system. Changed phones, this is on port 101. The line is not in use and this does not appear on any other phones. My version is 004. Does any one have any idea on how to clear this problem. Like I said it is not on any other phones and the line is not in use or lit up.

Thank you in advance for any helpful hints and answers

It is a missed call. Just press menu and scroll down to incoming call. Press enter
Clear numbers or just scroll through them and the call 001 will go

Thank you so much for this information! It cleared the problem. Someone had told me that I need to upgrade the system to clear this.
I appreciate you quick response.
