BT has lifted the lid on One Phone, a new service that brings together a company's office phone system and mobile phone usage into a single service, hosted in the cloud and delivered on a mobile phone.
All of an individual's numbers are linked to their work mobile phone, so whether somebody calls their landline, extension or mobile number, all calls go to one phone.
The service works with a full range of mobile phones by inserting a BT One Phone SIM.
Graham Sutherland, CEO, BT Business, said: "With an increasingly mobile and demanding workforce, businesses need communications technology that is as flexible as they are. Missed calls mean missed business."
BT One Phone provides inclusive on-net internal calls between users within a business, a choice of company shared bundles or unlimited voice and text tiers, and access to billing data.
To install BT One Phone, in most cases BT will build a dedicated mobile network in a customer's premises. When an employee leaves the office there's a handover between their dedicated mobile network and the BT Mobile national network.
