SIP is now rapidly replacing traditional ISDN and PSTN services.
Our SIP telephone lines connect your site directly into our network via an IP connection to carry and terminate your inbound and outbound voice calls across the public telephone network. They are a reliable, cost-effective voice service both cheaper and more flexible than traditional digital or analogue phone lines.
Millions of people already have first-hand experience of VoIP through services like Skype which was originally aimed to allow free or low cost calls to be made over the internet. Such services have grown in sophistication & reliability and are now widely used on a daily basis for both voice calls and data in the modern day workplace.
Through a single internet connection, our SIP telephone lines allow you to divide your broadband bandwidth between voice calls and data. This means that the development and falling prices of SIP telephone lines has made VoIP a necessity for modern businesses.
