Business SIP Trunking


SIP trunking is a flexible, low cost alternative to ISDN lines for inbound and outbound voice calls and also allows your business to experience the benefits of a hosted IP solution.

You can save on call costs and line rental charges, and calling and network features, in comparison to traditional fixed line service. If you are unable to take your new fixed line phone number to your new office, a Business SIP trunking service means you can use area codes from anywhere in the UK and point your business number to your SIP Service.

With Business SIP, we can provide automatic fallover to your other sites, the ideal solution in the event of a disaster or unforeseen event, such as an office power cut, to keep your business running.
