Explanatory diagram

The following diagram shows the installation of a Virtual PBX with locations in Milan and Rome.

  • you can move between locations while maintaining the extension number and configuration of your terminal
  • the Rome site hosts a Call Center with ACD groups
  • colleagues can work at both locations but use telephone services as if they were in the same location

Schema esemplificativo Centrex


  • activating a Virtual PBX is only possible at active Vianova locations
  • call forwarding to an external number is not available in Vianova profiles 1.1 and 1.5.1 (those with a single voice channel)
  • the maximum number of simultaneous external conversations is equal to the number of voice channels of the Vianova profile subscribed to
  • in the case of multiple geographic locations belonging to the same Virtual PBX, the maximum number of simultaneous external conversations per location, including those between the Customer’s sites, is equal to the maximum number of voice channels provided by the Vianova profile subscribed to (e.g. a Vianova 1.5 site will have 5 channels, a 6.12 will have 12, a 15.22 will have 22, etc.)
  • the quality of service (QoS) of the voice service depends on the correct configuration of the Customer’s LAN
  • the use of softphones (software applications on PCs) or of terminals connected to WiFi networks does not ensure the quality of the voice service


  • the core of the Vianova CentrexWIP platform is based on the Multitenant version of Kalliope PBX (www.kalliopepbx.com) and is implemented in collaboration with NetResults S.r.l., a company of the Welcome Italia Group
  • telephone traffic is billed by Welcome Italia according to the financial conditions provided by the Vianova profile subscribed to
  • the cost of calls transferred to extensions outside the Virtual PBX (national, mobile, international, etc. numbers) is that determined by the Vianova profile subscribed to for the CentrexWIP Vianova Multitenant PBX Platform
