Hello & Welcome to Just Answer,
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?

Hi again,
I didn't see a response to my questions, but I wanted to send the following information before I take a break for the evening.
Not knowing what particular model phone you have make this a bit harder to troubleshoot, but I can tell you that generally - when a system display something like "Check Tel Line", it means that there is some kind of "connection problem".
This connection problem could be ANYTHING from the actual PHONE CORD being disconnect from the phone jack in the wall to the phone SERVICE (from your provider) not working for a period of time.
What the "check tel line" message means is that the MAIN BASE UNIT of your phone system is NOT detecting a VALID PHONE LINE signal.
So the FIRST THING you will want to do is CHECK THE PHONE CORD between the phone base unit and the phone jack in the wall and VERIFY that the cord is well connected at both ends.
If you have a DIFFERENT PHONE you can swap in for the main base unit, I would do that - as a NEXT STEP in the troubleshooting process. Even a very BASIC corded phone would be good enough to TEST for a dial tone and if you can make calls.
Since this COULD be a problem with the phone service itself (from your phone company), the next step would be to give their TECHNICAL SUPPORT folks a call - using a different phone (cell phone, neighbor's phone, etc.).
I hope this helps. Please let me know what is found or if you have more information for me.
Thanks, ***** *****
