BT has launched a cloud-based mobile phone service, which is designed to ensure important calls are never missed.
The new BT One Phone links all of an individual's numbers to a single mobile, unifying their landline, extension and mobile phones.
According to BT, the service - which uses mobile broadband and Wi-Fi connectivity - will help businesses be more responsive to their customers, and ensure service levels are improved.
It works with a full range of mobile phones, simply by inserting a BT One Phone SIM.
Graham Sutherland, Chief Executive Officer at BT Business, said that with an increasingly mobile and demanding workforce, businesses need communications technology that is as flexible as they are.
"Missed calls mean missed business," he stated.
Mr Sutherland said the BT One Phone, combined with the upcoming launch of 4G services, demonstrates the firm's ongoing commitment to the UK's mobile workforce.
