Replacing your ISDN line with SIP trunks increases your business' flexibility and reliability.
Cloud Central’s SIP trunks give your existing PBX system a simpler VoIP system, while drastically reducing the monthly line rental cost.
Our SIP trunks are compatible with a wide range of IP phone systems. However, we can also use your existing PBX system by enabling a SIP gateway solution, without making any changes to your hardware.
SIP trunks offer a more flexible and lower cost alternative to ISDN for inbound and outbound voice calls. Compared with ISDN, our SIP trunking service is less costly and more flexible in how and where geographic telephone numbers can be used. It’s also quicker to install and provision and delivers exceptionally robust business continuity.
Any business with a PBX can switch to our SIP trunking service and immediately benefit from more flexible, less expensive and more resilient phone service.
Save money on call costs and line rental
SIP delivers cheaper, more reliable connectivity than ISDN over an IP connection. It could save you up to 50% on line rentals and 25% or more on call costs.
Free internal calls and great features
SIP is ideal for medium or large organisations with multiple sites. Not only will you save on your line rental and call costs, but you will also have the benefit of free internal calls within your organisation along with a host of other great features.
Scale up and down when you want
SIP trunks are the perfect solution for a business that is moving, upsizing or downsizing and who wants to keep existing numbers. You can scale up during busy periods and down again afterwards. You can add lines, take them away, split calls at any time – which means that you are always in control.
Built-in Business Continuity
SIP trunks can handle emergencies easily. They are inherently disaster recovery/business continuity ready, allowing you to reroute calls to an alternative location quickly and easily.
Compatible with Skype® for Business
Our SIP trunks are integration tested and approved to interoperate with Microsoft Skype® for Business, allowing you to connect to the platform to make external calls directly.
