Here are the AC-211-SR/AC211SR Config items mentioned in on my blog

Get your ViaTalk Credentials

• Log into the ViaTalk Control Panel
  • https://support.viatalk.com/billing/user.php
• Goto the softphone config (at the bottom)
  • https://support.viatalk.com/billing/user.php?op=menu&tile=softphoneconfig
• Get the generic configuration
  • Note your username, password and select one of the servers mentioned. Pick a server that is geographically close to you. You will need this information later.

Break into the Gizmo

Check this page for information on getting into the Gizmo as Admin. Logging in with password of welcome will not give you admin settings.

Configure the Gizmo

• Goto http://192.168.251.1/ and login with admin password.
• Goto WAN in the gizmo settings and turn off auto-configuration. If you don't it will keep getting overwritten with sunrocket settings
• Under LAN I added some additional port forwarding settings. I am not sure these are necessary

• Under SIP
  • Primary and Secondary server port is 5060
  • Domain name is vtnoc.net
  • The IP address can be the domain name viatalk sent you. ex newyork-1.vtnoc.net pick another local server as a secondary
    • Here are a few servers (you can use the IP or the name) Using IP address will ensure it works if there are DNS issues but using the name will ensure it works if the IP address changes.
      • For newyork-1.vtnoc.net IP address is 216.246.50.94
      • For newyork-2.vtnoc.net IP address is 64.118.82.164

    • DO not use the Dial plan mentioned on the viatalk forums. I could not dial out with this one
