2. How do I know what level of 9-1-1 Service I have with my VoIP phone?
You need to research the features of your VoIP service as it pertains to emergency dialing by accessing the service providers Web site. Search providers Web sites for emergency calling. Once you are aware of the 9-1-1 limitations, you need to notify all potential users of the phone (spouse, children, babysitters, etc.).

3. How is my 9-1-1 call routed to the correct location? 
When you sign up for VoIP that has automatic 9-1-1 service or when subscribing to optional dialing 9-1-1 service, you fill out a short form that tells your actual physical address. When you dial 9-1-1, your call is routed from the VoIP network to the general access line in a 9-1-1 call center associated with the service address you provided when you signed up.
In order for 9-1-1 emergency dialing to work properly, the service address on file for you MUST correspond to the physical location of your VoIP phone. This will enable your service provider to accurately identify your emergency Public Safety Answering Point and correctly route your call. You cannot specify a P.O. Box.

4. What if my 9-1-1 call is misrouted to the incorrect 9-1-1 answering point? 
If your VoIP 9-1-1 call is not routed to the correct 9-1-1 answering point, you should tell the call taker the city, county and state where you need help. The call taker can attempt to transfer your emergency call to the correct answering point. It is a good idea to know what police, fire or sheriffs department is responsible for your 9-1-1 calls and have their 10-digit phone number on hand to provide the call taker. 

5. Does 9-1-1 know where I am when calling from my VoIP phone? 
It depends on your service provider. The first information you will need to provide or verify for the 9-1-1 call taker is your location, name, and telephone number, especially if the emergency service personnel does NOT have this information available automatically. When this occurs, your call goes to a general access line at the answering point, which is different from how traditional 9-1-1 calls are routed to an emergency call center.

6. Can I call 9-1-1 from my VoIP phone when I'm traveling?
If you have emergency dialing activated and have mobile VoIP service with your provider, service is portable to any location with broadband Internet access. You may call 9-1-1 no matter where you physically reside. However, when you are not at the physical location that you entered in your customer profile, the call will not route to the proper 9-1-1 call center. Dialing 9-1-1 will automatically route your call to the local emergency personnel location for the address on file, not your temporary location. If you relocate your VoIP phone on a temporary basis, such as taking it with you when you go on a trip, don't use it to get emergency help. Use another telephone to dial 9-1-1.

7. What if my 9-1-1 call is disconnected?
Unlike traditional 9-1-1 service, the 9-1-1 call taker will usually not be able to call you back if you are disconnected. They often will not have access to your phone number. If you are disconnected, hang up and dial 9-1-1 again.

8. Do service outages affect my ability to call 9-1-1? 
It may. Just as your regular cordless phone will not work without power, your VoIP phone may not work without power either. As a result, you may be unable to make any calls, including those to 9-1-1 during an electrical power outage. 
Similarly, you may not be able to make 9-1-1 calls from your VoIP phone if your broadband service provider has a service outage or if any other service disruptions keep you from being able to make any outbound call. 

9. Do I need to notify someone if I move? 
Yes. When you move, you must update your new location on your service providers Web site. It may take several days to update your record. 

10. Should I keep my traditional phone line after I subscribe to VoIP service? 
Yes. 9-1-1 industry leaders recommend that you keep your traditional phone line in addition to your VoIP phone service in order to successfully access 9-1-1 services and to have telephone access during a power outage.

11. Do I need to tell anyone in my family that I have changed our phone service? 
Yes. It is very important that all persons that live in your home understand the differences in emergency calling with your new VoIP service. Children and babysitters always need to be educated on how to call 9-1-1 in an emergency. You might want to post your phone number and address by the phone for easy access.

12. Will my home/business security monitoring service work with my VoIP service? 
It might, but it might not. Check with your VoIP service provider to see if they support analog modem traffic such as burglar alarms, fax machines, Tivo Digital Video Recorders, etc. 

13. Can I make a 9-1-1 test call from my VoIP phone? 
It depends. Before doing so, please contact your law enforcement agency on their non-emergency line. Confirm that you are in their 9-1-1 jurisdiction and then ask if you can place a test 9-1-1 call. Many 9-1-1 call centers will comply with this request as long as they are not too busy with other emergency calls at the time. They may ask you to place your test call at a certain time.
