The end of ISDN telephony: prepare your company for all-IP in 2018!

Christian Rupitsch | 26. Januar 2018

Telephony is facing major changes as traditional ISDN telephone networks face immediate extinction. Many telecom providers have already been working for years to replace their old networks with the all-IP technology. This has a far-reaching impact on all companies that use their own ISDN telephone systems. In this blog article, learn what you must consider when ISDN is switched off and why IP telephony can also bring many benefits to your company.

IP telephony is also called internet telephony, cloud telephony or voice-over-IP telephony and very generally means making telephone calls over data networks using the internet protocol (IP). It replaces traditional ISDN telephone connections (basic or multi). IP telephony enables calls using smartphones, computers and laptops with a headset, and of course also using conventional SIP-enabled desk phones. The only requirement is a good internet connection, which most companies have. 

Why the ISDN switch-off affects your company

The ability to make phone calls over the internet is the technology of the present. The advantages of IP telephony, such as quicker data transfer and lower costs, have finally prevailed over the ISDN landline. Even if there are still many misconceptions about voice-over-IP, such as the call quality being worse (false!), the replacement of the traditional ISDN telephone networks is imminent.

For example, Deutsche Telekom is planning to switch off telephony and ISDN networks by the end of 2018 and to convert all existing telephone lines to all-IP by such time. This also brings far-reaching changes for companies that will no longer be able to use their old telephone equipment. 

What you should consider for the switch from ISDN to all-IP

Sooner or later, your company’s telephone line will be replaced. For years now, the major telecom operators in Germany have been accelerating the change to all-IP and they are certainly the pioneers of the changeover. Currently, Deutsche Telekom alone is converting around 60,000 telephone lines each week! This development will of course not pass Austria and Switzerland by, which is why a rapid technological transformation is to be expected here too.

For companies, the important question to be asked is: What do I do? After the ISDN network is turned off, your old telephone system may possibly only be usable with a “converter” (ISDN to IP). In reality, this is only an emergency fix and a play for time – it is better that you plan for a future-safe solution now!

The change to a new IP solution is unavoidable if:

  • your existing telephone system must be replaced (e.g. because the hardware is obsolete)
  • you would like to or have to save costs on telephone calls (e.g. elimination of expensive maintenance contracts and high telephone charges)
  • your telephony should become more flexible (e.g. integration of mobile phones, home office, external employees and project partners)
  • you would like to integrate new domestic or foreign locations into the telephone system
  • you have just established your company


Prepare your company for all-IP – first steps:

1. Find a provider

With the changeover to IP, you are no longer tied to your current telephone provider. This means that you can change to a new VoIP telephone system from a provider of your choice, where you can benefit from new functions and more economical prices, for example. Discover now the possibilities of switching over and obtain quotes!

2. Verify the capabilities of your current telephone system

If you only exchanged the hardware of your telephone system during the last 1-3 years, there is a high probability that you can also continue to use it in the “IP age”. Check in the telephone system manual whether it is SIP-enabled. If it is, then a simple connection via a so-called SIP-Trunk is very likely an ideal solution for you!

3. Plan the VoIP switchover

If your current telephone system is not SIP-enabled (and therefore not suitable for SIP trunking), if you are planning new locations for your company or if you have only recently established your company, you should deal with purchasing a VoIP telephone system. These offer you many advantages such as more flexibility and cost savings, quite apart from the necessary technology transformation.

 

Why all-IP is the better ISDN

New technologies bring not only change, but they also generally bring improvements. If you are struggling with the imminent transformation of telephony, rest assured: all-IP offers a host of advantages compared with ISDN, which will bring considerable benefits to your company and its employees. 

1. Flexibility and efficiency through new functions

Benefit from many intelligent functions that VoIP telephony offers you: for example CTI integration (call telephone contacts from Outlook), make calls using your PC with a headset, individual announcements, call forwarding, night time and vacation switching, call sequence, telephone conferences, blacklists/whitelists, and much more. Integrate the new telephone system with your existing CRM and merchandise management systems, e.g. to know who is calling you just as the phone rings. All these options make your internal and external communication more flexible and efficient! 

2. Cost saving

As most companies already have an internet connection and router, as well as smartphones, computers and headsets, almost everything is available for telephony over the internet. There are hardly any acquisition costs.

You also make savings on its usage: you only pay for the extensions you really need. With our VoIP solution atms IPBX, the costs are only €5.90 per user. Also, you can make international calls between all locations within the company free of charge!
 

3. Mobility

IP telephony allows all end devices to be integrated into the system. In addition to typical desk phones (SIP-enabled), this also includes smartphones, DECT cordless devices, computers and laptops. This means that you and your employees can take calls in comfort and from anywhere - worldwide!
 

4. Scalability

Is your company currently growing, or do you regularly have temporary (major) projects with external employees? Extensions and functions can be expanded or decreased at any time and as needs dictate.

Read in this case study how the IT company ITSDONE was able to join together several locations at home and abroad using a new VoIP solution. 


5. Self-administration

You control the cloud telephone system yourself using an online tool (also for mobile devices). You are not dependent on external specialists and you don’t waste time on appointments and additional costs. If you do require assistance, you can count on us as a VoIP provider for in-depth support at any time!

Conclusion: ISDN is being turned off - this is an opportunity!

The change from traditional telephone networks to more flexible and economic all-IP technology is in full swing. Every company is affected by this change and should take measures in good time. But do not view the changeover as a burden: IP technology offers many opportunities for your company and supports you in shaping your internal and external communication considerably more flexibly and efficiently!
