Building of conventional fixed and mobile telephone networks is very expensive, but operating such a network is very stable and of high quality.  Building a modern VoIP is low-cost and easy, but operating it may be unstable and quality may suffer.

The entire connection of VoIP networks to fixed and mobile ones is very complicated technically and very demanding financially. The entire interconnection of many dozens of national VoIP networks is practically impossible and a big amount of calls then usually runs via fixed networks.

In most countries, important data about all telephone networks are not centrally registered or easily accessible.  FUD strategy (fear, uncertainty, doubt) about reliability of VoIP networks is spread. Most telephone operators have maintenance centers for their own networks, but have no view on how other telephone networks function.

Prices for transit of calls via fixed and mobile networks are significantly higher than via internet connection of VoIP networks. Costs for purchasing one's own maintenance centre of telephone networks are extra high.

The xPhoNet Centre of Telephone Networks combines advantages of TDM and VoIP telephony, eliminates disadvantages and brings solution to above mentioned problems. xPhoNet could be a basis for further stage of development of telephone networks. As a result, further substantial decrease of prices of national and international phone calls can be achieved. xPhoNet aspires to have a positive impact to further demonopolization of telephony.

The xPhoNet systems are applicable:
1) At the international telephone network (provided by the licensor).
2) At public country telephone networks (to be provided by a partner sought).
3) At operator´s public telephone networks (to be provided in future)
4) At corporate private telephone networks (to be provided in future).

In domain of public telephone networks, the xPhoNet system is applicable as a “roof“ over many fragmented VoIP networks and as a substitute of the world proprietary network Skype.
