Maintenance/Web/Telnet Access; Advanced/System Features - Grandstream Networks GXW42 Series Settings Manual

4.2.1.2 Maintenance/Web/Telnet Access

This page will allow you to disable the telnet console and specify new passwords for user and administration
access to the Grandstream FXS Gateway web configuration.

It is recommended to set "Disable telnet" to "Yes" to close the telnet port to secure your network.

It is suggested that you set a non-default password for user and administration access (and record the
password so that the gateway can be accessed or modified later).

4.2.1.3 Advanced/System Features

The Grandstream FXS Gateway allows the phones on the FXS ports to call to other VoIP enabled devices without
going through the server and allows phones connected to it to access the menu system used for system setup.
For security purposes you will want to disable this functionality.

Set "Disable Direct IP call" to "Yes" to forbid dialing to other VoIP enabled devices without going
through the server.

Set "Disable voice Prompt" to "Yes" to disable the menu system on phones connected to the FXS
Gateways so that users at the phones cannot change the FXS Gateway settings.
