It’s Time to Make the Move to All-IP Telephony. Here’s Why.

PSTN providers throughout the world are making moves towards all-IP offerings. BT has announced plans to move to all-IP by 2025, and Deutsche Telecom has notified its ISDN customer base of plans to migrate its entire technology to IP by the end of 2018. So, what does this mean? In short: the end of ISDN and traditional telephony is drawing near.

Much has been written about the benefit of IP to business. In a nutshell, the technology provides advanced communications features that create greater business efficiency and improve customer service. The IP network design, although initially complex and calling for robust security measures, provides a worry-free solution with excellent scalability and reliability.

Recent announcements such as Snom IO offer businesses the tools and flexibility to develop innovative telephone applications tailored to their specific needs for increased competitive market advantage. Additionally, IP networks come out on top in a number of other areas compared to ISDN: They are easier to install, configure and manage, offer significant savings in monthly call costs, reduce wiring within buildings and eliminate vendor lock in — all the while providing innovation capabilities and feature rich applications.

Although IP offers plenty of business benefits, the move away from ISDN toward all-IP is in large part driven by costs for the operator — and indirectly by the equipment supply market — since few manufacturers still offer ISDN equipment or classical switching technology. It is also driven by pure economics. The evidence says that, financially, it is time for businesses and operators to make the move to all-IP.

For many years, telecom providers and businesses have remained attached to antiquated communications networks, which force them into countless cost and energy inefficient deployments. Advances in technology now make it possible to deploy efficient technology with considerable cost savings. Migrating to IP has been proven to eliminate approximately 70 percent of energy costs, according to US studies. This equates to billions of euros in power savings. The benefits on a global scale are enormous, and these savings are available to businesses of all sizes and in all markets.

German publication Computerwoche also reports that an all-IP approach will reduce the amount of water required for cooling by around 70 percent. It will also reduce CO2 emissions by an estimated 40 percent. All of this means that the move to all-IP actually pays for itself both for the operator and for the customer thanks to reduced energy and other costs. It removes the financial risk of network transformation while delivering a cleaner and greener infrastructure. This is a huge opportunity for the telecoms industry to do its part in aiding the environment while empowering sustainable business.

Thanks to the announcement of ISDN switchoff, businesses are becoming increasingly aware that IP brings a host of benefits in nearly all areas of telephony. There’s only one conclusion to be drawn: Now is the time to move to all-IP!
