What is British SIP Trunks?

SIP trunking is a standards-based replacement for traditional ISDN. It connects your PBX to the PSTN via broadband, ethernet or private circuit into our national network.

With 10 million UK businesses without a geographical telephone number, there is a huge customer need for SIP trunking. Our UK SIP trunking solutions are targeted at these smaller businesses and offer incredibly competitive pricing, easy installation and provisioning and extensive business continuity feature such as three hot switches over options and secure remote support.

The service is designed to meet the needs of small businesses, medium businesses and contact centres. The service supports connections ranging from two channels for small PBXs connected to a single L2 switch to unlimited channels for larger businesses connected to multiple L2/L3 switches, including data centres connected via Gigabit Ethernet.

Standard IP PBX systems do not natively support SIP trunking. Our SIP trunk works seamlessly with each of the leading IP PBX brands in the UK market. View the PBX vendors we work with.

Why upgrade to SIP?

Save money on call costs and line rental
SIP (Simple Internet Protocol) delivers less costly and more reliable connectivity than ISDN over an IP connection. SIP telephones and end points like the ATA100 series can save up to 50% online rentals and 25% or more on call costs.

Free internal calls and great features
Whether you're an organisation with multiple sites, or just looking to simplify your communications, our Cloud Solutions are for you. You'll not only save on line rental and call costs, but have the peace of mind knowing you're backed up by our award-winning customer service.

Scale up and down when you want
With SIP Trunks you can quickly and easily add more lines as your needs change. If you're moving, downsizing your phone plan or upgrading to a new phone, it doesn't require a trip to the phone company. You'll save money on having multiple different bills, too!

Built-in Business Continuity
To our customers, your business is everything. But even without a disaster, there are plenty of reasons to keep at least one SIP trunk ready for an emergency. 

British Voip understand that running a business can be challenging, but we're here to help. We don't just distribute services and products, we're a powerful voice in the market, making sure that businesses like yours succeed.

How resilient is SIP trunking?

SIP trunking is the future of business communications. We are the UK's largest provider of SIP trunking service, offering UK businesses low-cost, flexible, high-quality voice services.

We're committed to offering the best SIP Trunking service available in the UK. Our products are designed to meet your needs, whether you're an SME or a large business. We have a range of Trunks to suit any business that wants outstanding value for money and excellent service.

What happens if you lose power or internet connection?

If there was a terrorist attack in London, and the London branch of your business had to close, you can route calls to your Manchester branch instantly through SIP Trunks. If the London office were still open, they would also be connected to the call via SIP Trunks.

Your customers won't know that you've moved your office, but without SIP Trunks, they would have to wait for their service to be reconnected. Thanks to SIP Trunks, you can minimise disruption

What if you want to add or remove some of your lines?

SIP trunks are extensions that allow businesses to forward incoming calls to their employees. Businesses manage their incoming calls more effectively and allow them to work from home.

There is a lot of talk in the SIP Trunking space about the cost savings businesses will be able to make when moving their voice traffic onto an IP network. However, the reality is that for many businesses, the cost of ISDN lines is very cheap, often free or included in office rental. The real benefit of SIP Trunking is the increased flexibility and reliability provided when using SIP Trunking rather than ISDN.

What's the quality like?

With the built-in redundancy of SIP trunking, you can be sure that your telephone system is always available for business. This eliminates the risk of a single point of failure, and ensures that if one of our data centres goes down, your service won't be interrupted.

SIP trunking is a form of communication that allows companies to share their communication infrastructure. SIP trunking has become very popular in the last few years, but it has some issues that need to be addressed.

What if we're moving office? 

Reduce your call costs with SIP trunking. We can supply you with an unlimited number of free calls to any UK landline or mobile number, or any international number for that matter, all at the rock bottom prices you'd expect from a professional VoIP service provider.

With the flexibility of our CLI you can even decide which number to display on a call by call basis, so you can have your business number for one client and your mobile number for another.

SIP allows you to extend your business network quickly.

SIP Trunks are used throughout the world to connect to this platform, and allow users to make calls using their phone number. They are tested and approved by Microsoft for interoperability with Skype For Business.

The Janet community needed a reliable and cost effective way of connecting their members together, and the best way to do that was through a partner. Our partner operates a network on top of our network, giving them the ability to provide voice services over the internet to their customers.
