What to do next

Register the SIP Account Trunk on the third-party software or device. Depending on the network of the third-party software or device, you need to provide different information:
- Same local network as Yeastar P-Series PBX System
  - SIP Account Trunk details
  - Local IP address of PBX
  - Local SIP port of PBX
- Different network from Yeastar P-Series PBX System
  - SIP Account Trunk details
  - Public IP address, External host domain name, or FQDN domain name of PBX
    Note:
    
    If the account trunk uses public IP address or external host domain name, you need to configure the network and port forwarding first.
    For more information, see Configure Network for Remote Access by a Public IP Address or Configure Network for Remote Access by a Domain Name.
    
    If the account trunk uses FQDN, make sure this account trunk can perform remote SIP registration via FQDN.
    For more information, see Configure Network for Remote SIP Access by a Yeastar FQDN.
  - External SIP port of PBX
To receive inbound calls through the trunk, you need to select this trunk to one or more inbound routes. For more information, see Set up an Inbound Route.
