Replaces VoIP the public telephone network

Transmission of voice over the Internet

The abbreviation VoIP is being read more and more recently, but what exactly does it mean? VoIP is often mistakenly translated as Internet telephony, but this is not entirely correct. VoIP stands for Voice over Internet Protocol, as voice transmission over the Internet protocol. VoIP is used to express how the voice is transmitted, but not yet Where it is transmitted whether on the Internet or in a private network.

With classic installations, there are 2 networks in the company: a network for telephony with a private branch exchange and a connection to the telephone network and a network for data communication with corresponding network components such as switches or routers.

This is an expensive solution because 2 networks have to be built, operated and maintained in parallel. Since speech in digitized form is ultimately only data, nothing is more obvious than the idea of ​​also transmitting speech via data networks. Since the Internet protocol is used in almost all data networks today, the basis for VoIP has been laid. VoIP is also gaining ground in the public telephone network, largely unnoticed by the subscriber. In the medium term, VoIP will completely replace traditional telephony (analog or ISDN).

Two types of VoIP offerings
The VoIP offers in the public telephone network can be divided into two categories: The so-called 2nd line offers, which - as their name suggests - are used in addition to existing telephone connections. Such offers are not a full replacement for existing telephone connections because they do not offer certain functions (such as dialing emergency numbers or so-called value-added service numbers) and because their quality and availability are always at the level of what is currently available. In addition, such offers often only exist within closed user groups with no or only limited access to the PSTN. These 2nd line offers include classic Internet telephony (e.g. Skype), which is mainly used by private end customers to make free calls.

1st-line offers, on the other hand, offer the same or even more functionalities. They meet the legal requirements and offer the same quality and reliability as conventional telephone services. 1st Line VoIP is a full replacement for the conventional telephone and can be used by both private and business customers. MeliCom VoIP solutions are 1st line products.

Additional advantages
Another advantage of VoiIP is the optimal possibility of connecting computer and telephone (CTI Computer Telephony Integration, i.e. integration of telephony in the computer) and thus making telephoning more convenient thanks to a large number of performance features.

With NATJA (Nnetworkaadapted Telephone for jedermann aconnectable) from the Darmstadt-based manufacturer DAFÜR GmbH and the IP system family from the Sindelfingen company innovaphone AG MeliCom offers a professional selection of IP PBXs for every type of company.

The systems can be bought and installed at the end customer's premises, or they can be rented on a pro rata basis. In this so-called “Hosted PBX” variant, no investments in system hardware or software are required, you only pay a monthly rental fee based on the number of telephones used, which can be expanded or reduced easily, flexibly and at short notice. The integration of branch locations, home offices or mobile phones can also be done cost-effectively
