In the past, companies exchanged information by voice or fax via the analogue (PSTN) and digital (ISDN) telephone network. Today, staff holds videoconferences on their PCs, exchange information via instant messaging, collaborate in remote meetings with desktop sharing and use corporate applications via the cloud. Everyone can work from everywhere, at any time. As a result, the demand for network capacity has multiplied. Meeting this demand calls for a move to fiber optic connectivity and IP (Internet Protocol) as the underlying network technologies. All communication, both data and voice, takes place via one integrated IP network with redundant capacity.
We are evolving fast towards a network economy where everything is available, all the time, everywhere and instantaneously. This development is occurring parallel to a technological trend among manufacturers of network and communication appliances to convert analog and digital connections to SIP (Session Initiation Protocol) in telephone exchanges, for instance. Consequently, the current ISDN or PSTN systems will soon become outdated. Now more than ever, it is crucial for companies to have a clear view on the modernization of their own ICT infrastructure. Updating your telephone exchange creates the ideal opportunity to adapt the entire infrastructure and considers consolidating via IP data,voice traffic and your telephone exchange.
One of the main assets of Voice over IP is the wealth of media communication. VoIP protocols (such as SIP) run on the application layer and can work easily with other applications such as e-mail, web browsers, instant messaging or social network applications. Some examples include delivering voicemail via e-mail, click-to-dial on a website or call button in an e-mail. Nothing but advantages for the management of your ICT infrastructure as well. By integrating data and telephone via IP, you only have to maintain one network, which saves costs. It can also have a positive impact on call costs, particularly for connections abroad because international sites are now placed on the same IP virtual private network (VPN). Finally, the integration between data and voice can also facilitate Fix-Mobile Unification. This is a service where fixed and mobile numbers are linked to one another in the telephone exchange and the network so that you can be reached by phone whichever number you are called on.
We always want to offer our customers the best possible network experience, on both mobile and fixed lines, for telephone and data alike. This is why we constantly work to improve, optimize and upgrade our infrastructure. A major new step is coming this year when our network is to be equipped with IP technology. New fiber optic lines are being installed on a large scale and existing ADSL customers are being upgraded in terms of speed to VDSL 2. This also means that on 31 December 2016 we will stop selling new ISDN-2 lines (basic access). If you still use this technology, there's no need to worry: Proximus will continue to support ISDN2 technology. So nothing will change for you. From then on line extensions or new connections will be offered in Voice over IP.
