VoIP or landline Which is better?

According to Statista.com, as of 2022, 41.7% of US households have a working landline phone. On the flip side, 54.9% of homes use a cell phone only. As landlines are phasing out, VoIP phone systems are becoming the norm. VoIP is cheap, but that's not the only reason why VoIP is popular in home and offices. It offers a plethora of features that make communication easier. In addition to this, advanced VoIP offers software integrations, which makes it easier for an organization to manage teams and improve their customer relations.

What is VoIP?

The technology involving Voice over Internet Protocol has been around for a while. VoIP transmits voice signals in the form of data packets. The adapter converts analog voice signals to digital. The digital signals convert to data packets before transmission. On the receiving end, the router decodes the signals.

VoIP uses packet switching, which makes communication efficient. Packet switching saves the bandwidth for communication. Data packets are transmitted when someone is talking. In the case there is silence on the line, no data transfer takes place. Hence, packet switching uses bandwidth efficiently.

You need an adapter to connect a regular desk phone to the internet. The phone connects to the adapter, and the adapter connects to the internet router. The ATA (Analog Telephone Adapter) performs two functions. It converts the voice signals to digital signals. It is also responsible for initiating and terminating a call. IP phones connect to the internet without the aid of an adapter.

VoIP service providers also have a softphone, a mobile app for making and receiving calls. AxVoice offers a softphone app support, too, so that users enjoy the benefits while on the go.

What is a landline?

Landlines involve circuit switching; switches connect calls from the caller to the receiver. A landline uses Public Switched Telephone Networks (PSTN). PSTN has been in use since the conception of landline phones. In the initial stages of landline, a human operator switched calls.

Now, this is done automatically with the help of circuits. Although copper wires connect into our phones, fiber optic cables are used in landlines today. The voice signals are converted to digital before transmission via fiber optic cables.
