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.
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
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'.
