The End of ISDN and Analog Lines Telephony Technologies

The end of the “old” telephone line

The change from the “old” line-based telephony to the modern packet-switched IP telephony, also called “Voice over IP” or “VoIP” for short, via the “Internet Protocol” (IP for short) may involve a little more work at first, but it also offers many interesting new possibilities that would have been impossible with the “old” line-based telephony.

Seizing opportunities

Many companies are using the shutdown as an opportunity to replace their old telephone system with a new one or to switch to a virtual telephone system hosted in a data center. The latter solution, also known as IP-Centrex or NetPBX, not only saves the acquisition costs for a new telephone infrastructure, it can also help to significantly reduce the costs of telephony in the company. This is because the extension of such an IP-Centrex can be used anywhere in the world where there is broadband Internet access. For example, expensive forwarding costs to cell phones can also be saved in daily use, because employees can be reached on the road via a suitable app on their smartphone using their familiar extension number.

Flexible use

In addition, IP-Centrex extensions can be added easily and can be canceled just as easily, which is very useful for projects such as trade fairs, events or similar.
If, for example, 18 additional extensions are required for a three-month project, they can be added quickly and easily and then canceled at the end of the project. This way, the costs for the additional extensions are only incurred for the duration of the project and all participants can be reached internally via the telephone system, regardless of whether they are in the office or elsewhere.

Home office

In this way, the implementation of home office workplaces can be realized much more cost-effectively than if a separate telephone connection with its own telephone number had to be financed for each employee on site in the home office. The employees can still be reached via the IP-Centrex extensions under their known extensions without having to pay for call forwarding. The only requirement on site is fast Internet access, via which the company notebook, for example, connects to the IP-Centrex in the data center using a software telephone or desktop telephone.

Confidential connection

Furthermore, VoIP connections can be secured against unwanted eavesdropping by third parties (e.g. industrial espionage, etc.) without too much effort. This encrypted transmission of calls was only possible in classic wireline telephony with a great deal of effort on the part of each subscriber and very high costs. With modern Voice over IP connections such as an IP-Centrex, on the other hand, call encryption is only a few clicks and settings away with some providers. Thus, our virtual telephone system virtuTEL implements no less than three different encryption options, each of which can be activated with just one click if desired.

HD telephony

Another advantage of IP-based telephony is the much better call quality, because telephone calls are no longer limited in their frequency spectrum, as was the case with the old wired telephony.
