Our company recently relocated their ONT to the opposite side of the property, but they forgot to consider how this would affect our phone system. They thought they could simply plug the RJ-11 phone line into a router's RJ-45 port and it would work, but we all know that doesn't cut it. What's a simple way to fix this issue without having to run a new RJ-11 line all across the building?

You can utilize a CATx run for phone lines without any hassle. Make sure you're clear about whether you're using RJ-45 or RJ-11 connectors when discussing this with others, though! It’ll help avoid any confusion.
You need a basic wire with two conductors to connect points A and B. It can be old-school silver-satin, Cat 3, or Cat 5. If there’s existing wiring you can use, just repurpose it with couplers. Plug an RJ-11 into each coupler to connect both ends.
You can definitely run telephone signals over a standard RJ-45 jack using Cat 6 patch panels. Just connect the RJ-11 phone line on your office side, and make sure the other end plugs into the phone system or the telco punch down. It's a straightforward solution.
The cable can be used, but the router or switch won’t work for this purpose. Just remember they aren't interchangeable for phone connections.
Consider exploring some FXO/FXS equipment that might help with your setup. There could be a creative solution waiting there!

Just to clarify, while you're on that topic, POTS lines usually use at least Cat 3 wiring in buildings, with many setups now using Cat 5 cables at the patch panels. It's all about making use of what you have!
