SIP Trunks

Our flexible SIP Trunking service can deliver the benefits of Voice over IP to your existing PBX, or simply help drastically reduce your monthly line rental charges.

The internet is now being used as the primary communications platform for most businesses, and the natural progression now is to utilise it to carry inter-site voice traffic at no cost, or use it to replace expensive ISDN or PSTN phone lines.

Newnets SIP Trunking is a relatively new service that realises the business benefits of Voice over IP technology in a very simple and cost effective way.

Benefits of SIP Trunks

• Reduce the quantity of ISDN lines and save thousands of pounds in line rental with little or no upfront capital expenditure
• Provide significant cost savings on your voice traffic with no complicated discount structure or long term commitment
• Provide resiliency to your voice communications as part of your Business Continuity and Disaster Recovery planning
• Consolidate you communications invoicing across your business with a single bill and a dedicated customer service team
• Enable flexible working in a controlled and manageable way while keeping the associated costs under control
• Bring your voice service more in line with your other IT services

How much could you save?

On top of this, as some portion of the calls being made will be traversing the internet, significant costs savings can typically be achieved on the call traffic in addition to the savings highlighted above.

Use your existing PBX
