The inability to receive inbound calls is directly related to the FonVantage® equipment's ability to
register with our proxy server. If the ATA or ATA/Router is not registered, the FonVantage® proxy server will
be unable to route calls to the device and ultimately to you. When a call is unable to reach your ATA or ATA/Router, FonVantage® will
route the call to your voicemail.
There are a few reasons your phone adapter may not be able to register with the FonVantage® proxies:
- Power outages
- Loss of Internet connectivity
- Router/firewall security options blocking FonVantage® traffic
If this problem occurs, reboot the Phone Adapter. To reboot the phone adapter, unplug the power cord
from the back of the device, for 15 seconds, and then plug it back in. This will initiate a new
registration request. Wait 5 minutes for the device to completely boot up, before attempting to make a call.
If you continue to have trouble receiving incoming calls, contact FonVantage Customer Service at 1-888-Fon-Vantage (888-366-8268).
