A durable and affordable alternative to new devices, are the phones from our Remanufactured line. Fully checked, tested, cleaned and reset with one year warranty! Below is an overview of the 3 different techniques that are used in practice.
An analog device operates on a regular telephone line. It is possible to connect 1 phone number to this line, which can be called. When the available phone line is in a call, a new incoming caller will hear a busy tone. It is therefore possible to start 1 conversation per telephone line. If you only have an analogue connection, the use of the internet during calling is not possible.
With a digital connection, you still call analogue. In this case, however, your phone line is split into a telephone line and an internet connection. You still have 1 phone number and are therefore available for a single contact at the same time. However, an ADSL connection allows you to make use of the internet during the call.
VoIP telephony or shortened IP telephony is Voice over IP. This involves telephony over the internet. With a VoIP subscription, the user gets a cabinet on which you can connect an analog phone. In this case, one can simply choose a phone that is suitable for the analogue line. In order to make an internet call with an IP phone, it is important to have a SIP account. The user then receives a special phone number that only works with IP telephony. The possibilities depend on the provider.
