I don't remember where I read it, but I think regular phone cable is good
for 2000-4000 feet depending on whether you use the 22 gauge or 24 gauge
cable. You can use Cat5e network cable to go a little further, and I would
probably use it for shorter runs also as the twisted cables help reduce
crosstalk interference.
In any case, you will probably have to find cable rated for direct burial.
Even if you run conduit between buildings, it can still fill up with water.
When I needed direct burial cable to wire up our house, my phone company
gave me a few hundred feet at no cost. I don't know if that's standard
practice or not, but it saved me a lot of time and expense.
I would run Cat5e cable as you may want to run a network connection some
day. I would probably run two cables while you have things open. Better
yet, install conduit between buildings and you can pull whatever you need
later.
On the other hand, I've been running VOIP phone service for quite a few
years. With cordless phones I don't even use that phone cable I buried
years ago.
