Configure call routing and usage rating for your voice services. Connect usage records, customer charges and inter-operator settlements.

From call to charge

Every call accounted for

This is the chain we implement: uthorise, route, record, rate and charge.

  1. 01

    Customer call

    Your customer places a call over SIP or WebRTC.

  2. 02
    Account
    Balance or credit
    Destination allowed

    Authorise

    Account, balance or credit limit and the destination are checked first.

  3. 03
    Rate per minute
    Carrier A
    Carrier BEconomy
    Carrier CFailover

    Route selection

    Carrier rates for the destination are compared. The cheapest route connects; the next one waits as failover.

  4. 04
    Answered
    Connected time
    Customer
    AI agent, if used

    Record usage

    Connected time, and AI usage when an agent joins, land on the right customer.

  5. 05

    Rate & charge

    Your tariff prices the call. The balance is updated and the charge joins the period invoice.

Implementation

From audit to release

  1. System audit

    Switches, carriers, rate decks, customer accounts and existing billing data.

  2. Module design

    The modules your service needs, with interfaces, data model and acceptance criteria.

  3. Build and integrate

    Routing and rating, carrier and payment connections, portals and your tariffs.

  4. Parallel run and cutover

    Rated records are compared with your current billing before cutover, and a way back is kept.
