    Optimized Availability

    Optimize your customer service with attractive service numbers and intelligent routing.

    • 0800

      0800 numbers are free of charge for callers - you bear the costs! They offer efficient call distribution, high customer satisfaction and protection against nuisance calls through junk call protection.

    • 0180

      With 01801 to 01805 you can use location-independent hotlines with shared costs. Ideal for information hotlines and legally compliant waiting loops. VIER also offers 01806 and 01807 for special tariff models.

    • 01806

      With 01806 you meet the legal requirements for free waiting loops for chargeable hotlines and benefit from the block rate - a fixed price per call, regardless of the waiting time.

    • 01807

      With 01807 you meet the requirements for free waiting loops: The first 30 seconds are free, after that a minute rate applies. Unused time can be used for later waiting fields.

    • 0137

      0137 numbers (MABEZ services) are suitable for polls with many short calls, e.g. on TV and radio. All calls are confirmed immediately by announcement - no waiting times.

    • 0900

      0900 premium numbers offer value-added services such as weather information, stock market data or advice. 09001 numbers allow flexible tariffs, e.g. free waiting loops in the fixed network.
