How we provide the Most Reliable VoIP Service

The nature of the Internet makes it extremely difficult to provide a highly available network without employing geographically redundant servers. We believe that domain name redundancy is also a very important part of geographic redundancy and that's why we use multiple domain names from multiple DNS providers. Even though the DNS providers we use are the most well respected in the business, there's always a risk of failure and we make it a top priority to protect against such failures.

Most VoIP Providers use a single domain name for VoIP services, web sites and email. This is very convenient for Customers when everything is running smoothly, but not so convenient when things go wrong and they cannot make or receive calls, access the web portal or send emails to their provider. Many VoIP consumers have been left in the dark over the years yet nothing much has changed in the way that VoIP providers approach this problem.

The use of Twitter feeds and FaceBook pages have helped with communications in times of network outages, but the correct use of multiple domains with DNS redundancy can prevent outages in the first place. Even though we follow the advice of DNS experts and build redundancy into our domain names at the DNS level, we have also devised additional methods of redundancy at the VoIP equipment and VoIP platform level.


VoIP2Go is not your average VoIP service and we believe that Geographic Redundancy is essential in order to endure natural disasters and DDoS attacks. If a VoIP device is unable to register for 5 minutes then we can set it to request a resync from our provisioning servers which are spread over three different data centers in the USA and UK. If our primary DNS provider is down, then we auto provision a backup domain name managed by an alternative DNS provider into each VoIP device. On top of all this, we use multiple VoIP providers like Anveo and voip.ms to connect calls and this offers even more robustness.

To avoid attacks from our own Customer base, we put checks and restrictions in place and we only allow Customers from certain countries to use our service. We split our Customers into small groups so that attacks on domain names used by one group of Customers has no effect on domains used by other groups. By segregating the essential components of our network, there's no need for the whole service to go down. The nature of the Internet means that it is realistic to have small sections of our network down for short periods of time, yet voice calls remain unnaffected and the overall service continues to function as normal.

In summary, SIP Servers in multiple data centers, web sites and email servers in different data centers to SIP servers, the use of domain names from different DNS providers and a well rehearsed plan of action for denial of service attacks ensure that VoIP2Go Premium subscribers are able to make and receive calls in situations where many regular VoIP subscribers would be left 'in the dark'.
