To add users in bulk, check the instruction provided by TeamMate.
As soon as your service provider assigns the DID numbers to the Trunk Profile, you can configure trunk settings for users:
- Enable trunk(s) for each user
- Assign trunks for each user
- Assign DIDs to each user
To configure trunk settings for users:
3.1 Log in to the Enterprise portal.
3.2 Go to Trunks and click Users. This leads you to the dashboard that shows each user within the Enterprise (except PBX users).
3.3 Click Configure Trunk User for a specific user.

3.4 Fill in the form with the detailed information. Consult the TeamMate documentation for a detailed description of the available fields.

You can check details about the SIP trunk user management here.
Now, the configuration is completed, and you can start using the service.
