Problems? If you get one-way audio, or cannot get a dial tone or cannot make/receive calls with your VoIP device, you are probably behind firewall. Your router's firewall (also known as NAT) is blocking certain operations of the VoIP telephone adapter or some of the settings of the adapter is not entered correctly.
If you are sure that your account number & password is entered correctly to your device, before trying to resolve this issue on your router or voip device, you can get all device settings (other than account number and password) remotely from our servers.
In order to receive configurations remotely go to ADVANCED SETTINGS tab and change the fields below:
- Firmware Upgrade and Provisioning: Upgrade Via HTTP
- Config Server Path: config.voipvoip.com/GS
Click on the "Update" button at the bottom of the form. Unplug your device from the power and plug back after 5 seconds to reboot the device. Device will now get settings remotely from our servers.
Test again to make and receive calls.

If the phone fails to login, please take the time to double check your configuration as above. If everything appears to be correct, the problem may be your NAT/firewall.
