Digital phone service using the internet
My internet provider is offering a digital phone service at a most cost that includes all the usual premium additions like call display, waiting etc plus including unlimited Canada-wide long distance.
This service according to the FAQ's that I checked is provided using the internet.
911 calls will have to go back through the provider for address info unless the person calling states their address clearly. If the internet is down, so is the digital phone service.
My unlimited internet currently is provided through a regular Bell landline and DSL.
Is this much different than people using cellphones for all phone services including 911. How does the EMS know where to go with a cellphone call? My cellphone has the locator that I have activated.
How reliable is the internet for the future? What other pitfalls should I query as it is a very cost-effective option. Please help me think this through.
