Internet Interruptions
ooma service depends on your Internet connection. If the Internet connection stops working, the ooma Tab 

blinks red, indicating that your ooma service is temporarily unavailable. During an Internet outage, you will not 

hear any dialtone. When using the ooma system without a landline, you will not be able to dial 911 unless your 

power and Internet connection are both working.

 If you are using your ooma system with a landline and you experience an Internet outage, you will hear the 

regular landline dialtone, not the ooma dialtone. You can still make and receive calls, including 911 calls, 

over your landline. However, all outgoing calls will be placed over your local landline and regular landline 

calling charges will apply.

Power Outages
If a power outage occurs, all ooma services are unavailable. The ooma Tab will go dark and you will not hear 

the ooma dialtone. When using the ooma system without a landline, you will not be able to dial 911unless your 

power and Internet connection are both working.

 If you are using your ooma system with a landline and you experience a power outage, you will hear 

the regular dialtone when you use your phone. You can still make and receive calls, including 911 calls, 

over your phone line if you have a line-powered corded phone. However, all outgoing calls will be placed 

through your local phone service, and regular phone company calling charges will apply.
