This could happen for a number of reasons. For example a power glitch or a temporary loss of Internet connectivity could leave the ATA or other networking equipment in a state where they are unable to recover.
Rebooting the affected equipment may restore your connection. Start by rebooting the ATA. If that does not solve the problem, a reboot of networking related equipment may be needed.
Rebooting the ATA
This may be necessary if you notice that the VoIP light on the ATA is off and you can’t make a ATA telephone call or if the Network light is off and you can’t surf the Internet from your computer which connects through the ATA. This may be due to an interconnecting cable having become disconnected or there might have been a power surge. So, first ensure that all the connections are secure. Then reboot the ATA, as follows.
- Unplug the power cable from the ATA.
- Wait 10 seconds, then plug the power cable back in.
- Wait 2 minutes for the ATA to boot up. When the lights on the ATA stop flickering and the VoIP light is on, it is ready for use.
- Pick up the receiver to confirm that there is a dial tone.
Rebooting other networking equipment
Thunderstorms, power outages and other sources of power surges can cause loss of synchronization and disruption of communication links. So, if you can’t make a call from your ATA telephone and/or can’t connect to the Internet, you may need to reboot your networking equipment. This consists of powering down, then powering up your equipment. You do NOT have to disconnect any of the interconnecting cables.
Power down each element in the order shown below then wait a few minutes and power them back up in the same order. To power off a device, turn its power switch off or unplug its power cable. When powering up, wait for each device to become ready before powering up the next one.
- Cable/DSL modem
- Router, if any
- Hub, if any
- Your computer
You should now be able to make a call using the ATA telephone or surf the Internet.
