In most cases, you will not be able to connect calls if there’s a power outage. Our VoIP phone system works over the internet. During a power outage, your router will not be able to function, which means there will be no internet access.
The only exception to this is if you have a backup power source that could power the router (and therefore maintain your internet connection). If you use Power over Ethernet (PoE), that may need backup power as well.
Vantact’s system can automatically re-direct calls to cellphones, softphones, PC or landlines automatically if your phones happen to go offline due to a power outage or internet outgage.
