Analogue phone or IP telephone – what’s the difference?

IP telephony, softphones, SIP, VOIP, the PSTN – the telephony terms can be quite confusing! In this blog post, we take a look at the differences between analogue phones and IP phones. 

Analogue telephone or IP telephone?

Traditional fixed phones with the physical telephone and handset have had a similar look since their invention in the late 19th century. On an analogue telephone, you call via the fixed, physical telephone network. The phone is connected to the analogue network via a cord.

In the early 2000s, a new kind of telephony, IP telephony, became increasingly popular. With IP telephony, you call via the internet instead of via the fixed telephone network. There are many benefits to IP telephony, and the cost of IP telephony is usually much lower than for fixed telephony.

IP phone, VOIP phone, or SIP phone?

A dear child has many names. Simply put, one could say that IP, VOIP, and SIP basically mean the same thing – audio and sometimes images streamed digitally via a network. Feel free to read more about the difference between VOIP and SIP here.

Physical phone or softphone?

IP phones are available in two different versions: a traditional, physical desk phone and a softphone.

Traditional desk phones usually include features like conference calls, Bluetooth, and speakerphone. A softphone is instead software on your computer or mobile. A virtual phone, you could say. A softphone has more advanced features. We have written more about how a softphone works here.
