Hello Wim,

the new Device is added to a User Object with basic configuration options by the Users App Service, adjusting a new Device of the User Object is done by the provisioning application.

The provisioning App Service:
- Receives "mt":"ProvisioningPhone" on the AppWebsocket to Users App Service
- Performs Device changes on the User Object
- Performs config changes on 3rd Party Phone
- Sends "mt":"ProvisioningPhoneResult" on the AppWebsocket to Users App Service

The Device changes on the User Object can be done by changing the User Object via PbxAdmin API or updating it via Replication API (this is in general a preferred method to keep User Objects on the PBX and App Service in sync).

Best Regards

Andreas Fink
