Via which type of telephone landline can you make calls?

To an analogue connection, link 1 telephone number with which you call. An advantage to analogue calling is that the phone always works, even if the power fails. On the other hand, it is not possible to link several telephone numbers, so you can only be reached on one number. When you are talking on an analog line, a new caller hears the busy tone. Do you only have an analog connection? Then the use of the Internet during calling is not possible.

With an (A)DSL / VDSL connection, you still make analog calls, but your phone line is split into a phone line and internet connection. The advantage of an ADSL connection is that you can still use the internet when you make a call. You still only have 1 phone number, so only 1 contact can reach you at a time. This makes DSL more common for home use than business use.

VoIP stands for Voice over IP, so internet telephony. Instead of calling via an analogue or digital line, you can call VoIP via the internet. This form of calling has the advantage that the call quality is better than with other lines. You also call against a lower fixed monthly amount. On the other hand, if you have a power failure, your telephone connection is out, because VoIP equipment is electric. Do you want to know what else you use VoIP for? Then read the article below.
