No, ring voltage is about 80Vac in the USA and can give you quite a shock.
Don't ask how I know....
A T1 span can have up to +-130 Volts of DC power superimposed on It. It will wake you up real fast.
So where all the phone lines of the plant I worked at some how had the same voltage of the 3 t1 lines. I guess I tested them. The guy who worked in the room run the servers and did daily backups said he would never go where I had to work I was uses to normal phone lines. I hooked my wire tracer in the office was trying to find it where the main trunk lines come in there's a wall with 10,000 lines on old lugs you use a nut driver not punch down. And it was hot the sweat on my hand and my side hit some that didn't have covers It's a shock you'll remember it hangs on to you LOL I thought It stopped my heart.
I later got to talk to the guy that handled the phones and t1 lines he said don't let it fool you these lines could kill you. I laughed I know I know it dang near did.

Yes, it is not just dc, but also ac superimposed on it. So ~80v ac, on top of ~48v dc, will not be what you may expect to feel.
I think we have drifted off topic. I am sorry. Does the OP have more questions?
