The point of this role is that the telephone maker makes phones for everyone so that they can use it. The person with the phone can chat with people who also have a phone. The people who are chatting does not know who is on the phone, not even the telephone maker themselves, the only way the telephone maker knows who is on the phone is that the telephone maker have to check who he/she gave the phone too. The people with the phones can use the phone for ever but here the catch! If the telephone maker gets killed or lynched, the people with the phones can't call anyone because the telephone maker was the one who set up the connections to the phones.
Also the phone is just like the party host's party meeting but it is not a one time thing!
