Phone voltage is normally low (under 50ish volts AC and DC), but when a phone rings it can kick out about 70 volts. You can get poked while working with the wires but its not dangerous like working 120V. Just work carefully and dont rush through it. If you have a newer network interface box on the side of your house. You can open it and unplug the wire in there and it will disconnect all phones in your house. Since you have a older phone, you may not have one of these.
Most newer phones release by pushing up on them, then pulling forward. On older phones there is sometimes a release button somewhere you have to push while lifing. If not, take a pic of the phone with the cover off for us. If you cant find the wiring block or connections but can get the phone off you can cut the cable after you pull the phone, just make sure you have enough to work with and it doesnt fall into the wall.
WHen you remove that phone you will see 2 to 4 wires. The only ones you need are the red and green. Tape off the others just in case they are still live. Connect red to red and green to green on your new jack and you are done. Test the new phone by making and then receiving a call.. if all works then you are good to go, If it doesnt work or you didnt find a red and green wire, you will need to trace through your house to find if someone got the wires crossed somewhere. It may be a good time to update the wiring too.
