What is a cloud-based phone system?
With a cloud-based digital voice system, you make your calls over the internet rather than the traditional phone network. Your call routing takes place in our secure data centres instead of in hardware installed on your premises.
It’s quick and easy to set up, with very little equipment to install or maintain. And our team of cloud systems experts are on hand if you need support.
How reliable and secure are your cloud-based systems?
When combined with BT internet access, you’ll get 99.99% reliability. And if you’re making calls over a dedicated BTnet internet connection, we’ll give you your money back if it isn’t available 100% of the time.
The data centres we use for our digital voice services are regularly audited. They have the latest firewalls and intrusion detection systems, and all of the data we handle is encrypted.
How does a cloud-based phone system work with my mobile?
There are several ways you can use your mobile phone with the system. You can set your mobile to ring whenever your office phone does, which is handy if you’re away from your desk or office.
With BT Cloud Voice and BT Cloud Phone you can flip calls between phones. So if you answer a call on the office phone as you’re heading out, you can switch the call seamlessly to your mobile.
Or with our mobile app (for Android and iOS devices), turn your mobile into an extension of your phone system, allowing you to set up call routing, transfer calls and much more.
How easy is it to set up a cloud-based phone system?
We make setting up as easy as possible, with simple plug and play options as well as ones we’ll come and install. And, we have a team of cloud system experts to call on if you need help along the way.
How much would I pay for a cloud-based phone system?
How much you’ll pay depends on several factors.
It depends on which system is best for your business and how it’s configured. The best thing to do is give us a call so one of our team can chat about how your business works and what you need.
What is VoIP and what is a cloud-based VoIP phone system?
VoIP (it stands for Voice over Internet Protocol) means that you make calls over the internet rather than over the traditional phone network. And with a cloud-based phone system, your call routing takes place in our internet-connected secure data centre instead of in hardware installed on your premises.
Are VoIP calls good quality?
Yes, you’ll get the same level of clarity as you do with a regular landline (depending on the set-up of your system and the internet connection, call quality may even be better). Calls made over your internet connection take priority over data, so you can be sure that your call quality will be consistent.
How easy is it to set up a cloud-based VoIP system (and what support do I get)?
We aim to make setting up as simple as possible, which is why you’ll have a team of cloud system experts to call on if you need help.
Our BT Cloud Phone system is the simple plug and play option where phones arrive ready to go. Just connect things together and we’ll talk you through how to set it up so it’s right for your business, including help with setting up call handling rules and user profiles.
BT Cloud Voice, which is ideal for businesss with more than 9 employees, is also a system that you can install yourself, but you've also got the option for us to pop in and set it up if you prefer.
