Create a Peer Trunk

This topic gives a configuration example to describe how to create a general SIP Peer Trunk, which can be applied to various peer trunk scenarios.

Prerequisites

You have obtained the server information required to set up a SIP peer trunk from the ITSP, such as IP address/domain, and port, etc.

Example information typically provided by an ITSP is as follows:
  • Provider domain: peer.voipglobal.net
  • Registration port: 5060
  • Transport protocol: UDP

Procedure

  1. Log in to Yeastar Central Management, go to Cloud PBX > Trunk Sharing > Shared Trunks.
  2. Click Add.
  3. In the Basic section, enter the general information of the trunk.
    Setting Description
    Name Enter a name to help you identify the trunk. The system will automatically append a 6-character random suffix (e.g. _M8D90A) to ensure the name uniqueness.
    Note: The name you enter can not exceed 56 characters.
    Trunk Status Select Enabled to activate the trunk.
    Region Select the region where the P-Series Cloud PBXs that will use this trunk are deployed.
    Note:
    • The shared trunk MUST be in the same region as the desired Cloud PBXs to ensure connectivity.
    • The region cannot be changed after the trunk is created.
    Select ITSP Template Select General.
    Remark Optional. Add a remark for the trunk.
  4. In the Detailed Configuration section, enter the SIP information provided by the ITSP.
    Setting Description
    Trunk Type Select Peer Trunk (DID Based) or Peer Trunk (Port Based) based on the type of trunk provided by your ITSP.
    Transport Select the transport provided by your ITSP. In this example, select UDP.
    Static IP Address & Port Provide the IP address and port to your provider for trunk binding.
    Hostname/IP Enter the domain name or IP address of the ITSP. In this example, enter peer.voipglobal.net.
    Port Enter the provided registration port. In this example, enter 5060.
    Domain Specify the domain for the SIP URI (e.g., in the From or To header).
    Note: If the ITSP does not provide a domain, enter the same value as Hostname/IP.
  5. Optional: Go to the Advanced and SIP Headers tabs to configure advanced trunk settings according to your needs.
  6. Click Save.

Result

The trunk is displayed in the trunk list. If the status shows , it indicates that the trunk has been successfully connected and is ready for use.

What to do next

Add DID numbers to the trunk and assign the DID numbers to PBX instances for trunk sharing.
