Unified Communications is a properly configured set of applications that previously functioned separately, which, by unifying them, offer even more. The platforms for Unified Communications combine instant messaging, voice mail, fax, e-mail and communication services in real time such as audio and video calls, audio/videoconferencing, collaborative work on the documentation, sharing computer desktops. An additional advantage of the UC platform is the possibility of work from anywhere and its limitless functionalities. The Unified Communications system is complemented by its ability to integrate with traditional telephones. If your company has PBX infrastructure, you do not have to resign from it. PBX phone users can contact the users of the UC platform. The users of the UC platform also are able to make calls on any phone number, including landlines, mobile phones and internal company numbers.
