### Answer --- Question 1: Sharing numbers across different workspaces Transferring phone numbers purchased through Retell between workspaces is not currently possible. [(1) ]() However, you can use a single phone number across multiple agents within the same workspace by using the inbound webhook with

override_agent_id

to dynamically route calls to different agents. [(2) ]() --- Question 2: Limiting agent access for different users in a workspace Yes, Retell has a Role-Based Access Control (RBAC) system with three roles: [(3) ]() - Admin – Full control over workspace resources and members - Developer – Can build and edit agents, flows, LLMs, KBs, voices, but cannot manage billing or organization users - Member – Read-only access to agents and configurations; cannot create, edit, or delete resources However, these roles apply at the workspace level, not at the individual agent level. There is no documented way to restrict specific users to only certain agents within a workspace. ---

### Answer --- Yes, that's correct. A phone number can only be imported to one workspace at a time in Retell. [(1) ]() If you want to use the same SIP-trunked number in a different workspace, you'll need to: 1. Remove the number from the original workspace – You can delete it from the dashboard or via the [Delete Number API]() . [(2) ]() 2. Import the number to the new workspace – Once removed, you can import it to the second workspace using the dashboard or the [Import Phone Number API]() . [(3) ]() , [(2) ]() Keep in mind this means the number will no longer function in the original workspace after deletion. ---
