Hello - is there a method to assign an unassigned extension to a user via the API? I tried 2 methods and neither worked so I am curious if I am doing something wrong or if there just isn't a way to do this yet.
I first tried using 'Update Device': https://platform.devtest.ringcentral.com/restapi/v1.0/account/accountId/device/deviceId
I used a deviceId of an unassigned extension and passed in the extension id of an existing user. This method resulted in the following error: "Unknown device update use case".
I then tried using 'Update Extension': https://platform.devtest.ringcentral.com/restapi/v1.0/account/accountId/extension/extensionId
I used the extensionId of an unassigned extension, and passed in the user contact information (the user did not exist in RC). The API request went through, but when I went to look in RC, the extension was still in the 'Unassigned Extensions' section and when I clicked on the link, it brought up a read-only page showing the contact info I added to the extension but nothing could be updated. I had to assign the extension to someone else manually to get the extension out of the 'Unassigned' list.
Any help/thoughts would be appreciated - thank you!
