If the ISP that supports VoIP goes down, the VoIP system can automatically switch to the other ISP so that there is no interruption in telephone service. Of course, having what is essentially a redundant Internet service will increase your Internet connection costs. The reality is that VoIP needs the Internet to work, just as today you need your local lines to work. If either service goes down, you can't make calls.
What do you do today if your phone lines go down? One of the things about the VoiceWalker service that is very attractive is that we are able, with the added features that you get from Hosted PBX over VoIP or, in many cases, even with the basic SIP Trunking service, is to have a disaster recovery plan that would allow all phone calls to be routed to an alternate number, whether it's a mobile phone or an alternate office location. This would work in both a power outage and loss of internet. It can be set up as an automatic failover or, you may not have set it up in advance, but we give you the ability to log into a web portal and implement a change on your own rather than having to wait for someone to do it for you. You can do it from a mobile phone internet connection, a laptop while sitting in a Starbucks, etc.
The only real requirement for using VoIP is a quality Internet connection. Home users, or small businesses, can get by with a decent DSL connection. Some VoIP providers (like us here at Tele-Data Solutions) can install a dedicated Internet line to your office if you only have access to a high-speed Internet provider in your area. So the big question is, how do businesses ensure that their communications are not dead in the water if their Internet connection goes down? The drop can be due to a number of reasons: an Internet provider or carrier problem, a problem with the local loop cabling, an accident that knocks down a pole or two, the failure of a piece of equipment in the local office network.
there are any number of problems that can cause the Internet (and therefore the VoIP service) to go down. So the problem lies in your Internet circuit? Because you're on VoIP, when the Internet goes down you lose your phones... Businesses considering the cost savings and benefits of VoIP should not worry about potential outages due to Internet or power outages, as many times the built-in failover offered by the VoIP provider will more than sufficiently maintain phone calls in the event of an outage. All VoIP providers are different, but some (like us) are able to offer built-in survivability in the event that the Internet connection powering a VoIP system goes down.
VoIP phone service (sometimes called broadband phone service or digital phone service) is a phone service that works using your high-speed Internet connection. Unlike traditional landline phones, VoIP uses your phone or computer to call the number over the Internet. An ATA (sometimes provided free of charge through your VoIP provider) can connect your existing phone to a high-speed Internet connection. Even if your Internet connection is up and running and there is a problem with it, your phone service may not work properly if your business is using VoIP.
