Assign DID Numbers to a P-Series Cloud PBX

This topic describes how to assign DID numbers to an existing P-Series Cloud PBX to associate the PBX with the corresponding shared trunk.

Prerequisites

  • You have available shared trunks (with DID numbers) in the same region as the PBX, under one of the following conditions:
  • The firmware version of the Cloud PBX is 84.19.0.22 or later.

Procedure

  1. Log in to Yeastar Central Management, go to Cloud PBX > PBX.
  2. Click beside the desired PBX.
  3. In the PBX details page, go to the Assigned DIDs tab.
  4. Assigned DID numbers to the PBX.

    1. Click Add.
    2. In the Shared Trunks drop-down list, select the desired trunk to share with the PBX.
    3. In the DID drop-down list, select the desired DID numbers to assign to the PBX for inbound call routing.
  5. Optional: Assign custom SIP headers of the shared trunk to the PBX, which will be included in SIP INVITE messages of the outbound calls routed through the shared trunk.
    Note: This setting is available only when the following requirements are met:
    • The firmware version of the Cloud PBX is 84.22.0.134 or later.
    • The shared trunk has been configured with the custom SIP headers.
    1. Click Add Header in the Operations column.
    2. In the Custom SIP Header drop-down list, select the desired custom SIP header.
    3. In the Value filed, enter a value for the SIP header.
      Note:
      • The total length must not exceed 255 characters.
      • This value MUST be unique across all Cloud PBXs for the same custom SIP header on the shared trunk.
    4. To assign more custom SIP headers to the Cloud PBX, repeat step a to c.
  6. Click Save.

Result

  • The trunk automatically appears on the Cloud PBX (Path: Extension and Trunk > Trunk), with an indicator of showing that it is a shared trunk.

  • Any changes made in the trunk in Yeastar Central Management are automatically synchronized to the PBX.
    Note:
    • Trunk settings managed centrally through Yeastar Central Management can NOT be modified on PBX. However, PBX administrators can configure the Inbound Caller ID Reformatting and Outbound Caller ID settings for the shared trunk.

    • Shared trunks are NOT included in PBX system backups, whether the backup is performed on the PBX or via Yeastar Central Management. After restoring a PBX, you need to reassign shared trunks and the corresponding DID numbers for the PBX in Yeastar Central Management.
