Why can’t I receive any calls on my IP phone ?

Why can’t I receive any calls ?
Some reasons why your IP phone adapter may not be able to register with our servers:
• Possible power outage
• Internet connectivity has been lost
• Router/firewall options have blocked VoIPVoIP traffic
Please check that you have Internet connectivity (try to view a few web sites) and check if your router/firewall settings have changed and do not block the VoIP traffic.
