If your Internet Voice Tracker was setup properly and has worked in the past and suddenly today its not working, this is usually a problem with your internet connection.

1. Either your IP Address to the station has changed
2. or the internal IP Address to the on-Air Computer has changed.

For Number 1 above, you can use a service like DynDNS to maintain your stations correct IP address.  After you setup this account, you will use a word like wxyz.dyndns.com instead of an IP Address like 123.45.67.89.  This is the BEST way to maintain a connection to your station.

For Number 2 above, Each time you reboot a computer at your station, this little thing called DHCP will assign the computer an internal IP address that looks like 192.168.0.125.  The bad part about DHCP is that when you reboot a computer, it may get a new internal IP address.  The Port Forwarding that you setup will now be broken.

Changing the On-Air computer from DHCP to a hard coded internal IP address will solve this issue.  Now when you setup the port forwarding, it will always work because the internal IP address will NEVER change.

If you impliment both of the above recommendations, you will have no issues with Internet Voice Tracking.
