VoIP Trunks Introduction

VoIP Trunks are phone lines that transmit calls over the Internet. A VoIP provider can assign a local number to one or more cities or countries and route it to the PBX phone system. Usually VoIP trunks are cheaper than traditional PSTN trunks.

VoIP Trunk Types

Yeastar Cloud PBX supports the following VoIP trunk types:

  • VoIP Register Trunk: Registration based VoIP trunk. VoIP Register Trunk uses the username and password for registration with SIP providers.
  • VoIP Peer Trunk: Uses the IP address & port or domain of PBX for authentication or connect PBX directly to VoIP provider's dedicated network. Your VoIP provider routes incoming and outgoing calls based on the DID number, PBX port or PBX domain, or route calls by a private network.
  • VoIP Account Trunk

    Account Trunk is designed for connection between Yeastar Cloud PBX and other devices. Yeastar Cloud PBX will act as a VoIP account provider, the other device should register this account to connect to Yeastar Cloud PBX.

  • WebRTC Trunk

    A WebRTC (Web Real-Time Communication) trunk is used to set up WebRTC Click to Call. After you create a WebRTC trunk on the Yeastar Cloud PBX, a link will be generated automatically.
