Change the Administration Password

We strongly recommend that you change the default password for the root

administrative account using the following steps:

1. Enter the password you chose in step C again in the Confirm Password to

ensure that there were no mistakes in the initial entry.

2. Press Submit.

VoIP Configuration

The 4300T provides a VoIP application layer gateway (ALG) for the SIP,

MGCP, and H.323 protocols. The ALG proxies the connection between the

VoIP softswitch, IP PBX or gatekeeper and voice and video devices such as IP

phones, IADs or softphones. By acting as a proxy the 4300T is able to provide

several important functions for IP based voice and video:

• Provide NAT/PAT services for voice and video traffic. NAT/PAT for

VoIP enables you to use a single public IP address on the WAN interface

of the 4300T to represent multiple private IP addresses assigned to voice

or video devices on the LAN. The NAT function maps both IP address

and IP port number between the public and private addresses so that all

signaling and VoIP media packets are translated. A single public IP

address can support up to 253 voice and video devices.

• Provide security services for voice and video traffic.

— NAT/PAT services hide enterprise LAN topology from hackers.

— The ALG acts as a “voice and video aware” firewall and ensures only

authenticated voice traffic enters the enterprise LAN. This is

accomplished by the dynamic provisioning of signaling and media

ports for authenticated voice devices. The implementation is stateful

and open ports are closed automatically when no longer required to

support the voice or video call.

Note

The new password must be between 6 and 20 characters in length. Any

combination of alpha and numeric characters is accepted.
