Our switches/servers maintain a 99.999% uptime with performance and processes continually
monitored by specialised software.

VOIP (Voice Over IP)
VOIP is a technology which enables you to make calls via an IP (Internet Protocol) connection,
the same type of connection used for browsing the World Wide Web.
To enable you make VOIP calls a hardware IP phone or a software IP phone is required.
These phones use a number pad just like a traditional telephone and are just as simple to use.
Many different technologies are available to facilitate VOIP, H.323 and SIP being the most popular.
We use SIP (Session Initiated Protocol) an open standard which has wide support.
Although VOIP is possible over dial-up connections we recommend a broadband connection via ADSL or wireless technologies.
Satelite broadband connections are not recommended due to latency issues (long round trip delays).
It's a common misconception that the quality of VOIP is less than a standard phone line.
In fact the quality of VOIP is dependant on the bandwidth of the IP connection and coders/decoders used for the call,
the quality may actually be far superior. Typically the quality will be as good if not better than a
standard phone line.
VOIP calls can be made and recieved to/from the PSTN (Public Switched Telephony Network), ie. a standard phone line,
if a PSTN gateway is used. All our paid VOIP services can make and receive calls to/from the PSTN as if on a standard phone line.
