    • Realtime billing
    • Block calls on negative balance (prepaid) or balance under credit limit (postpaid)

    • Daily balance email to customer
    • Limit the maximum number of calls per customer and/or per gateway
    • Multiple contexts

    • Powerful LCR engine
    • Routing based on area code
