END USER CONFIGURATION

Once the HTTP request is sent from a web browser, the user will see a log in screen. There are two default passwords for the login page:

User Level:	Password:	Web pages allowed:
End User Level	123	Only Status and Basic Settings
Administrator Level	admin	Browse all pages

Only an administrator can access the “ADVANCED SETTINGS” configuration page.

NOTE: If you cannot log into the configuration page by using default password, please check with the VoIP service provider. The service provider may have provisioned and configured the device for you. The Basic Configuration Page is the first web GUI the user will see.

Important Settings

The end-user must configure the following settings according to the local environment. NOTE: Most settings on the web configuration pages are set to the default values.

NAT SETTINGS

If you plan to keep the gateway within a private network behind a firewall, we recommend using STUN Server. The following three (3) settings are useful in the STUN Server scenario:

1.STUN Server (under Advanced Settings webpage)

Enter a STUN Server IP (or FQDN) that you may have, or look up a free public STUN Server on the internet and enter it on this field. If using Public IP, keep this field blank.

2.Use Random Ports (under Advanced Settings webpage)

This setting depends on your network settings. Generally if you have multiple IP devices under the same network, it should be set to Yes. If using a Public IP address, set this parameter to No.

3.NAT Traversal (under the Profile web pages)

Set this to Yes when gateway is behind firewall on a private network.
