We have web app serving many extensions/users in our organization.

This app uses a single RC API token (using its own extension, that has all the permissions we could come up with). Is it possible for that App to make CallOut (not RingOut!) API calls for devices associated with other extensions? We need something like a click-to-call feature, where users trigger a call-out from their softphone via the browser (posting that request to the server).

We are successfully making CallOuts to devices when they belong to the app's extension, but whenever we make CallOuts for other devices we get

Error CMN-102 - Resource for parameter [deviceId] is not found
