Is Telnet safe to use?
Short answer. No. It sends everything, including passwords, as plain text.
What does VoIP do?
It turns voice into packets, so calls travel over the Internet.
Three protocols
| Protocol | Job |
|---|---|
| PPP | Two nodes |
| Telnet | Remote login |
| VoIP | Internet calls |
Remember
| Telnet is not encrypted |
| SSH is the safe choice |
Telnet sends your password as plain text. Is that safe? Three more protocols. PPP joins two devices directly. Telnet logs in to a far computer. VoIP carries voice calls. Stay safe. Telnet is not encrypted. Use SSH instead.
