FAQs

  • What is wholesale voice termination?

  • Are voice termination and routing separate services?

    Prasmo brings voice termination, routing and interconnection together as one Wholesale Voice service. Interconnection establishes how your platform hands over calls, routing determines their onward path, and termination carries them towards the destination network.

    Prasmo’s service proposition includes call detail record (CDR) reporting, destination-level performance information and traffic analytics. Our team can confirm the reporting options available under your proposed service arrangement.

  • How long does it take to go live?

    Prasmo’s onboarding process is designed to help customers go live in days. The actual timeline depends on commercial agreement, technical readiness, interconnection configuration and successful testing.
