How Voxbone’s SIP trunk service works

  1. Incoming voice calls, faxes and text messages to Voxbone phone numbers are locally converted to VoIP (SIP) by a Voxbone VoIP / media gateway.
  2. The converted calls, faxes and messages are routed via redundant IP links to the nearest Voxbone PoP.
  3. The calls are then transferred to the customer’s data center, anywhere in the world.
