02: Telephone number administration

O2 needed a system for telephone number management: telephone-number reservation and administration as well as number porting in mobile and fixed-line networks. ConSol developed telephone number management systems for O2 and is now responsible for servicing all applications in this area.

In addition, ConSol is responsible for 3rd level support including infrastructure and middleware diagnosis as well as further development corresponding to user, technology and interface requirements. Last but not least, ConSol supports O2 in its daily operations. This requires precise knowledge of business processes and regulatory laws as well as of the software infrastructure.


  • O2's entire telephone number management is in one hand
  • Cost savings: Synergy through know-how and problem and incident management
  • Guarantee for the highest possible professional support service
