Mix and match your Wave subscription to match the needs of the users within your organisation. For instance, if you have the back-office personnel primarily managing inbound calls, opt for Wave 100 licenses. For those engaging in a substantial volume of outbound calls, the Wave 3000 license would be more suitable.

Frequently asked questions

How is Wave different to traditional phone systems?

Wave is a cloud phone system (or a “hosted phone system”). This means all the software that runs it is based in a data centre, with calls being delivered into your office via an internet connection. This removes the need for a local PBX on site, which helps to offer additional flexibility.

How do I set up additional users for my business?

Simply give our team a call on 01225 800800 and they can set up extra users in a matter of minutes.

Can I transfer my existing business number?

As long as we have a porting agreement in place with your current provider, we will be able to move over your current telephone numbers. Our experienced team will complete the necessary porting documentation and manage the order through to completion.

Do you offer residential packages?

Sorry! We currently only supply voice and data services to businesses and partners.

Can I make and receive calls on my mobile phone?

You will have access a ‘soft phone’ which is an app installed on your mobile phone. This will allow you to access all the features from your office phone and make calls from your office number. You can also make calls via any computer using a web client.

Can Wave support multiple sites?

Provided each of your sites has an internet connection (and we can help you get one if not) you will be able to utilise our cloud phone system across your business premises.

We’ve helped organisations from across the UK take advantage of cloud-based communications tools. Can we help you?
