Assign Trunk Access Permission to Users
On Yeastar Central Management, you can grant subordinate users the permission to assign your shared trunks and DID numbers. This allows them to provision these resources directly to their managed cloud PBXs, while you retain full control over the trunk configuration and management. This topic describes how to assign trunk access permission to subordinate users to achieve this.
Requirements
The firmware of Yeastar Central Management is 87.17.0.80 or later.
Prerequisites
You have created shared trunks and assigned DID numbers to them.
Procedure
- Log in to Yeastar Central Management, go to .
- Click Add.
-
In the pop-up window, complete the following settings.

- In the User drop-down list, select the user to grant permission to.
- Click Add.
- In the Shared Trunks drop-down list, select the desired trunk.
- In the DID drop-down list, select the desired DID number(s).
- Click Save.
- Optional: Repeat step 2 and 3 to assign trunk access permissions for other users.
Result
-
The assigned trunk access permission is displayed in the Trunk Access Control list.

- The users with this permission can either
assign the shared trunk and DID numbers to cloud PBXs under their
management, or assign these trunk resources to
their own subordinate users. Note: However, the users cannot view or modify these trunk resources in their Shared Trunks list. The authorized trunks only appear as selectable options when they are assigning trunks.
