What voice and data infrastructure technicians (cable guys) do quietly without a lot of fanfare gives the impression that it is easy and it actually is. It is easy in both ways. It is easy to do correctly if you know what your doing and on the flip side it is easy to make a fatal error if you don't have experience. Let me recommend these things.

Put 2 cat5e cables to every possible location that you think will need either a phone, a computer or both.

Waste cable! When you think you have it long enough add 6 feet.

Do the same in the room or location where the data and voice equipment will be located. Each cable that goes in that room should be able to go on any wall all the way to the floor then waste 6 more feet.

You only have one chance to do it right the first time.

Stay in touch, your gonna need us!
