RTCBT_POLL
This polled buddy does not have a continuous presence subscription, meaning the server will not notify the application of any changes in the presence status of the buddy. The application must call the IRTCBuddy2::Refresh method to obtain the current presence status of the buddy. The polled buddy cannot be persisted on the SIP Server or in a local storage file. This type of buddy cannot be added to a buddy group. The presentity URI of this type of buddy cannot be changed via the IRTCBuddy::put_PresentityURI method.
