We have a telephony platform, and we are striving to change the presence status of Lync users based on events on the telephony platform. We would rather use the UCWA REST api, as we are familiar with the REST api and already have most of the infrastructure.
By checking the documentation, it quickly becomes apparent that the user can establish his own presence. However, we do not want to track authentication information for each individual user. Instead, can some users (presumably users like the administrator) change the presence status of other users using UCWA? Any other practical possibilities for managing the presence of Lync users from outside presence?
