From the past to the future: How to make the move from ISDN to SIP

Gamma’s team of telecoms experts offer practical advice on the main steps you can take to successfully migrate to SIP trunking, with insights on how the Open University succeeded in making the transition.

Why switch to Gamma?

Apart from the savings, you’ll be with one of the UK’s biggest providers of voice services and voice applications for business in the UK. Because we’re business only we can focus on giving our customers the most reliable business-grade services coupled to the most responsive customer service.

Our next-generation national IP network is one of the largest voice networks in the UK and interconnects with all the other major providers, enabling us to provide the very best service at the very best price.

Gamma has become one of the fastest growing businesses in the UK telecommunications market over the last few years.

Can I keep my existing phone number?

Yes. Contact us and we’ll switch you onto our network so your calls are routed automatically. No need to dial any prefix numbers or install special equipment.

How quick is the transfer process?

We can transfer your existing lines and calls to Gamma within 10 working days. We’d love to do it quicker for you, but this is an industry standard timeframe that we can’t change.

Are my calls protected from fraudulent activity?

CallGuard is our phone management tool that ensures you don’t fall victim to the ever-growing threat of phone fraud and hacking. CallGuard can protect your business from criminals hacking into your phone system and making expensive international calls using your phone number. With CallGuard activated on your lines, our network detects unusual usage and automatically bars the line, meaning that you are only ever liable for the calls up until the bar is in place, giving you peace of mind that your service is being constantly monitored.

How much can I save on my phone bill?

Send us one of your current phone bills and we’ll show you how much you can save with Gamma. You could be saving as much as 35% on your phone charges – some businesses make even greater savings.

How will I be billed?

We’ll make life easier for you by providing your calls and lines on one simple, detailed bill. If you take other Gamma services as well, such as our broadband or mobile services, they’ll all appear on one bill – which is accurate and easy to understand. We’ll give you a log in to your own online portal through this website, so you can access your bill at any time.

Are my calls Carbon Neutral?

All Gamma calls are Carbon Neutral, meaning that customers using our service are using an environmentally-friendly service that has net zero carbon output.  This is important to many businesses and organisations that need to comply with environmental policies, particularly in the public sector where carbon reduction is a key objective. Using Gamma helps you to demonstrate your Green credentials. We are CarbonNeutral® certified by The CarbonNeutral Company, a world-leading provider of carbon reduction solutions.
