VoIP to cut your landline bill: €15 a month that doesn't always materialize

VoIP to cut your landline bill: €15 a month that doesn't always materialize

An IP phone inherited from a company that upgraded its switchboard, a second-hand adapter for 20 euros, and a question many people ask themselves when looking at their bill: why keep paying 17 to 18 euros a month for a landline that almost nobody picks up? The idea is simple. Port your long-standing number to a VoIP provider charging 1 to 2 euros a month, plug a gadget into the router and let calls travel over fiber. On paper, the savings come to around 15 euros a month, some 180 a year. In practice, things get more complicated.

What you need to set up VoIP at home

The basic equipment isn't expensive. A two-port adapter like the Linksys PAP2 goes for around 20 euros on second-hand platforms, and you can plug any ordinary cordless phone into it. The advantage of this setup is that if something breaks, you only replace the faulty part. Dedicated IP phones, on the other hand, start at higher prices and many have been discontinued.

Configuration isn't always intuitive. The provider's manuals aren't enough, and some people end up copying settings from competitors' guides. When the phone can receive no calls but can make them, the problem usually lies in the router's NAT: the SIP server can't find the device. It's fixed by enabling mapping and keep-alive options, or directly with STUN.

Is it worth dropping the landline from your fiber provider?

It depends on who you ask. Some argue that providers bundle the landline with fiber no matter what, and that fighting to remove it is a waste of time. Others point out that data-only plans exist, like those from some operators without a phone line, which let you do without the traditional line. The difference between the two routes can be 3 euros a month once contracts and promotions are factored in.

The profile that benefits most from the switch is the frequent international caller. A VoIP provider lets you call foreign landlines for cents, and those with family abroad notice it. Someone who uses only their mobile for everything, on the other hand, will hardly get their money's worth from the hassle.

The problems that appear once it's set up

Sound quality depends on the provider. Some users have gone years with the same service without a single issue, while others report recurring dropouts and failures. The bill can also hold surprises: one provider charged 50 euros for what the customer thought was a domestic call, after finding that the destination number was being used to route international traffic.

Another limitation is emergency numbers. Without a landline tied to a specific address, 112 or 091 won't know where you are. And if the power goes out, a traditional phone keeps working; VoIP doesn't.

Alternatives competing with the landline

Messaging apps and internet voice services cover a good share of domestic calls. Some argue that a mobile is enough to talk to friends and family, and that setting up a VoIP infrastructure at home is using a sledgehammer to sustancia ilegal a nut. The usual reply is that for serious business you need a phone number people can call.

Fax still comes up in the conversation, even if only as a relic. Some providers let you receive faxes on the same SIP line by enabling it in the control panel, and daily users get a second number.

The full calculation, with the breakdown of contracts, promotions and adapter costs, yields a difference that doesn't always justify the switch. And yet, the underlying trend is clear: more and more people look at their landline bill and wonder why they're still paying for it.
