Detailed Business Description

Callsure Business Telephone Services can help you keep your existing phone number when you move premises.
Our Number Porting service allows you to move your Landline phone number away from your existing provider & use it no matter where you are physically located in the UK or across the world.
This allows you to receive calls to any device for a fraction of the cost. You can also make outbound calls & display your existing number as your Caller ID.

- Receiving calls only on a mobile phone

    Helpful and friendly service

    Recently I had the pleasure of dealing with John from Callsure who was super helpful in solving my business dilemma. I needed a service that allowed me to received calls from two different organisations on the same handset - but I also wanted to clearly find out which one was ringing me so that I could answer appropriately. John set me up with two landline numbers and a call whisper feature that tells you which organisation is ringing before you answer. I also was able to customise the voicemail message that is heard if I didn't answer in time. A very professional and cost effective service that will be invaluable to my business. Thank you Callsure, I wouldn't hesitate to recommend your services.
