Voice Features
The TA612V Broadband Voice Adapter lets you use the full range of features in your voice
account.
• Get your voicemail messages by phone, Web, or E-mail.
• Turn call waiting on or off. Easily switch between calls when you are using call waiting.
• Use Caller ID with any phone device that has Caller ID enabled. You can also block your
Caller ID when you make a call.
A Powerful, True Firewall with Content Filtering
Unlike simple Internet sharing NAT routers, the TA612V is a true firewall, using stateful packet
inspection to defend against hacker attacks. Its firewall features include:
• Denial of Service (DoS) protection.
Automatically detects and thwarts DoS attacks such as Ping of Death, SYN Flood, LAND
Attack, and IP Spoofing.
• Blocks unwanted traffic from the Internet to your LAN.
• Blocks access from your LAN to Internet locations or services that you specify as off-limits.
• Logs security incidents.
The TA612V will log security events such as blocked incoming traffic, port scans, attacks, and
administrator logins. You can configure the router to E-mail the log to you at specified
intervals. You can also configure the router to send immediate alert messages to your E-mail
address or E-mail pager whenever a significant event occurs.
• The TA612V prevents objectionable content from reaching your computers. The router allows
you to control access to Internet content by screening for keywords within web addresses. You
can configure the router to log and report attempts to access objectionable Internet sites.
