ZyXEL Communications 28641 user manual ∙ PAP sends the user name and password in plain text

8.Outgoing: My Login Name - This is a required field if Call Direction is either Both or Out. Enter the login name for the Prestige when it calls this Remote Node.

9.Outgoing: My Password - This is a required field if Call Direction is either Both or Out. Enter the password for the Prestige when it calls this Remote Node.

10.Outgoing: Authen - This field sets the authentication protocol used for outgoing calls.

The Prestige supports two authentication protocols: PAP (Password Authentication Protocol) and CHAP (Challenge Handshake Authentication Protocol).

∙PAP sends the user name and password in plain text.

∙CHAP scrambles the password before it is sent over the wire.

Generally speaking, CHAP is more secure than PAP; however, PAP is readily available on more platforms. The recommendation is to use CHAP whenever possible. Turning off the authentication is STRONGLY discouraged.

Options for this field are:

∙CHAP/PAP - Prestige will try CHAP when CHAP is requested by the Remote Node or PAP when PAP is requested by the Remote Node.

∙CHAP - use CHAP only.

∙PAP - use PAP only.

11.Outgoing: Pri(mary) Phone Sec(ondary) Phone Number - Both the Primary Phone number and the Secondary Phone number refer to the number that the Prestige will dial to connect to the Remote Node. The Prestige will always call the Remote Node using the Primary Phone number first. If the Primary Phone number is busy or does not answer, the Prestige will call the Secondary Phone number
