Before you set up a trunk in Power Trunk, make sure your organization has the required licenses and user permissions.
Required licenses
Each trunk in Power Trunk requires three core licenses (provisioned by your partner administrator in Sales Hub):
| License | What it does | Required? |
|---|---|---|
| Power Trunk (Base) | Activates one trunk in your portal (with built-in SIP Trunk connectivity enabled by default). If you need multiple trunks, purchase one Base license per trunk. | Required |
| Concurrent Session | Sets the maximum number of simultaneous calls allowed across the trunk. | Required |
| Number | Assigns fixed-line DIDs or toll-free phone numbers to the trunk for incoming and outgoing calls. | Required |
Optional licenses
- B3 Own Recording: Required on the License page if you want B3 to record and store your trunk's call audio natively (instead of streaming to an external SIPREC recorder). Your recording session count must not exceed your trunk's Concurrent Session count.
How do third-party apps and AI agents appear in Power Trunk?
When your organization purchases its first Power Trunk base license, the platform automatically enables the default User, AI, and Recording applications approved by your partner in Business Hub > Power applications.
User permissions
Access to Power Trunk depends on your organization role and whether you have been granted access to a specific trunk:
| Who | What they can do |
|---|---|
| Organization Owner / Super Admin | Can view and manage all trunks in the organization automatically. |
| Assigned Admin or Member | When added in the Admin section of a specific trunk, can view and manage only that assigned trunk without needing full organization admin rights. |
| Custom Role User (View-only) | When granted View Power Trunk permission under Manage Organization > Roles & Permissions, can view trunk settings in read-only mode without making changes. |
