It’s all Internet and VOIP what’s on the clock. News media make you believe that old analogue telephony is a dinosaur and you need to quickly switch to the latest IP technology. But is that the case?

We often don’t think about it, but there is still a lot of analogue telephony used. Perhaps not so quickly in a home situation, but think of a large production hall, a power station, railway tunnels, hotels, elevators, or situations where emergency and waterproof and explosion-proof phones are required. Here, the costs of a modern wired and active network do not outweigh the simplicity of two-wire passive technology.

The susceptibility to interference due to environmental factors such as magnetism, electricity, vandalism and moisture, but also the dependence on electricity and the distance to be covered quickly show that the reliability of an analogue telephone is not even that bad. Often the environmental factors have a strong influence on the choice of technology, but it should not be the case that you let the technology dominate the desired deployment and then choose a digital solution.

Analogue phones use simple and cheap copper cables, are reliable and often speech quality is very high. Add to that the low price and you will see that in various environments this is an ideal choice.

But we should also not forget that analogue telephony is less modular, has higher support costs, is more difficult to configure and is not easy to upgrade.

But should we really choose? No, fortunately not, there are also a number of good hybrid solutions available in the market where you can seamlessly integrate both worlds. The cabling is two-wire and the phone analog, but a “gateway” is able to convert this into IP and thus offer the flexibility and scalability.
