John Doe is using a phone, typically now it's a cellphone, but up until about the 1980s it was a Pay Phone or in rare cases, his or another person's home phone. Richard Roe decides he needs to use the phone. Richard will either interrupt the call (for a pay phone or a home phone) or steal or confiscate John's cell phone. If Richard Roe just takes the phone and isn't planning to give it back, that's stealing. If a police officer or public official takes a phone because there's an emergency, that's a confiscation, because presumably the owner will eventually get the phone returned.
In the case of a pay phone or other landline, seizing a phone to use for a call is actually legal in the United States if you have an emergency. Now, how do you know what is an "emergency"? Well, every telephone book in the United States had a notice defining what an emergency is. "An emergency is a situation where life or property is in jeopardy and the prompt summoning of aid is essential." What that means is if your car got hit and no one is injured, you don't have an emergency, i.e. you can wait until the person finishes their call to get a tow truck. But, if your dog or cat was hit by a car, a dog or cat is "property" and not getting hold of a veterinarian or a cab "promptly" to take them there (for "aid") means your "property" is in jeopardy of dying, and this is a valid reason to demand emergency use of a phone.
In a lot of these cases, it might not be an emergency, it might be Richard Roe just needs a phone in a hurry and steals one. In an older work, when seizing control of the payphone, expect Richard to tell the person on the other end "He'll call you back" before hanging up and dialing their own call.

- This becomes an important plot point in one episode of the Korean series Class Of Lies (or Mr. Temporary). Korean teachers typically collect the students' phones before an exam and return it to them after the exam period ends. However, the undercover teacher Moo-Hyeok, who's the invigilator during the class' test, took this opportunity to hack and transfer data from Beomjin'snote phone to his assistant working behind-the-scenes. Beomjin finishes his exam early and asks for his phone, but Moo-hyeok's persistent refusal to give it back makes him suspicious of the teacher. Beomjin, then, reminds the teacher that he has the right to get his phone and leave since a certain period of time has passed. He eventually gets his phone back after a suspenseful back and forth with the teacher.
