Introduction to Unified Communications (UC)

Unified Communications (UC) refers to a new communication model that integrates computer technology with traditional communication technology. As a solution and application, its core content is to enable people to freely communicate data, images, and sound through any device and network at any time and any place. That is to say, the unified communication system integrates all types of information such as voice, fax, email, mobile short messages, multimedia, and data, bringing people freedom of choice and improved efficiency. For example, traditional telephones will be replaced with client software based on softphone screens. It differs from network level interconnectivity, but rather from the integration and collaboration of human centered applications, which is a higher-level concept for the new generation of communication and IT industries.

Unified Communications is the integration of video, voice, fax, email WEB, All types of information such as mobile short messages and multimedia data are integrated into one, which can be used for traditional telephones, IP telephones, faxes, mobile phones, 3G mobile phones, etc, PC、 Any kind of reception in handheld computers, Outlook, PDA and other communication devices builds an information interconnection channel between wired, wireless and Internet. The system can also determine the transmission method and whether to transmit information based on the user's situation, such as time and location. For example, implementing the H.320, H. 323 protocol, SIP protocol terminals and traditional telephone, fax, IP telephone, 3G mobile phone, PC desktop applications, data collaboration applications, interconnection with monitoring, program storage and playback, IPTV, VOD and other rich and powerful unified communication platforms.

1.6 The significance for enterprises

According to Microsoft's sampling survey results, 80% of business managers believe that the problems that arise during the operation of the enterprise come from internal communication issues. 50% to 75% of the information required for employees' daily work is directly obtained from other employees. More than 80% of the digitized information in enterprises is scattered on the devices of various employees. Without good communication, the enterprise cannot operate normally. With the development of information technology, employees in enterprises have access to an increasing number of communication devices. Is it true that the richer the means of communication, the better the communication effect? According to a report released by Sage Data Research, although the average person currently owns 6.4 different communication devices (including landline phones, mobile phones, email, instant messaging, office phones, etc.), there is still a 36% chance that enterprise employees cannot contact each other in the first place. Because these communication devices often work independently and there is no unified communication system established between them. It can be seen that only by effectively integrating various communication methods together can internal communication within the enterprise be made more comfortable and resource sharing easier. Unified communication can create a comprehensive information service platform for enterprises, integrate multiple communication methods, effectively improve employee work efficiency and enterprise resource utilization, and reduce production costs. At the same time, unified communication has changed traditional business models, allowing enterprises to quickly achieve instant communication with customers and partners, which helps them seize fleeting business opportunities.
