IP-Centrex

In English, this technology is often translated as "virtual PBX". Even today, in many IT departments terms such as "IP Centrex" are still foreign words. One synonym in current use is "hosted PBX" ("Private Branch Exchange") or "IP Centrex".

In contrast to a traditional telephone system, which is operated within the premises of the business using it, this new dimension of the telephone system is centralised and available as a web application. This kind of highly innovative telephone system also connects to the traditional telephone network, the only difference being that the connection between the telephones and the telephone system equipment is not a telephone cable, but an Internet connection. This means you can connect to your central telephone system from anywhere in the world via a wide variety of devices - from the classic corded phone, to DECT phones and laptops or desktop PCs with softphones and headsets, through to a mobile phone. Nconnect from NFON customers can also connect via a high-performance symmetrical internet connection (SDSL or SHDSL) at a uniquely favourable price.

Telephone systems from NFON are based solely on this new, highly innovative technology. The system facility itself is hosted on powerful servers in several geographically separated, highly redundant data centres.

With NFON technology, small and medium-sized businesses get access to all the features of a highly professional telephone system. You benefit from a functionality that was previously found only in expensive enterprise solutions and gain the possibility of adding extensions with just a few clicks, with unheard-of scalability and considerable cost savings.

The wide range of services available includes features such as voicemail, queueing, voice applications and telephone conference calls. Telephone calls are digitized by the IP phones in ISDN quality. The system telephones communicate with the telephone system in data centres via the local company Ethernet network and broadband data line (ADSL or SDSL). The servers in the data centre then make the collection to the public telephone network.

The distinguishing feature of "hosted PBX"

It is important to distinguish between solutions that are dedicated outsourced systems for a single customer alone and shared platforms (i.e. a true cloud application). In the first case a provider operates a single outsourced telephone system for a single customer. Here, the cost-saving opportunities are limited by the nature of the offer.

With NFON, all customers are provided with one and the same telephone system, meaning that even small businesses can use the full range of functions that a high-end PBX offers, just the same as the large corporations that have already switched to NFON. Of course, for data security reasons, customer records are kept strictly separate.
