Solutions for


Substitution of networked PBX’s and branch connections by an IP based carrier system.

State of affairs

Enterprises face the challenge to converge the growing data and voice information and optimise the costs at the same time. Enterprises with a decentralised structure face this challenge and they require dedicated personnel. IDB’s solution addresses this challenge and combines existing data infrastructures and voice connection of network operator with the high-grade performance features of a professional Carrier VoIP system. Customary solutions such as networked PBX’s show several functional disadvantages. Homogenous numbering plans or the integration of single branch connections may usually not be realised. The challenge is to optimize distributed networks with high operational and maintenance costs in terms of costs and functionality.


The solution IDB Enterprise Virtual PBX enables the full provision of voice services on broadband connections in the enterprise network. Utilising the virtual PBX functionality allows to implement solutions purely based on IP or combined hybrid solutions by including legacy appliances. The advantage of a hybrid implementation is the soft and cost optimal migration to a new solution. The advantages of such a new solution may be exploited on locations with legacy infrastructure.


  • Reduced complexity and administration
  • Reduced effort for modifications (move, add & change)
  • Enterprise-wide and structured numbering concept
  • Availability of several function packages per port
  • Guaranteed availableness due to pro active monitoring
  • Location autonomous telephony
  • Enhanced possibilities (XML, CTI, etc.), video and soft phones

Customer Scenarios

  • Insurances: Head office with several regional branches and several small offices with the option to include agents in the network.
  • Hospitals: Several large buildings with hundreds of connections on a compound or distributed on different locations including regional branch connections integrated in a large voice network. In addition the many changing connections of patients may be handled flexibly with prepaid functionality and auto-provisioning.
  • Networks of the public authority: Several regionally distributed locations of various sizes that usually are connected via subscriber’s extension stations.
  • Retailer: From regional to nation-wide distribution of small locations requiring voice, fax and data connections to regional or trans-regional exchange with a larger amount of ports. Often it is required to integrate the legacy equipment in the branches using gateways.
