IP Centrex
IP Centrex is a service of a virtual telephone exchange which can fully replace a branch telephone exchange of an organisation. The fundamental difference is that it is not necessary to acquire any exchange. All that is required is to have a data connection and IP telephones.
O2 Virtual exchange uses modern technology for the transfer of voice over data network using the protocol VoIP (Voice over IP). In contrast with VoIP of various providers, in the case of O2 Virtual Exchange there is no transmission of voice over the public internet, but over a dedicated channel with managed quality of transmission between the customer and O2 telephone network. This solution thus offers highly secured, high-quality and guaranteed transmission.
The functionality of IP Centrex allows the implementation and use of modern telephone functions.
As a result of the architecture of IP Centrex it is possible use a great number of above-standard services which are configured directly in the virtual exchange. The functions are available where they are necessary, not where the exchange is installed.
The technical equipment of O2 is in the secured, climate-controlled premises of data centres with high level of security, multiple securing of power sources and regular backing up of data. As a result of shared architecture and secured technologies, O2 can ensure maximum avoidance of any problem. The supervision and operation of the service are ensured by highly qualified O2 workers in non-stop operation.
