Abstract
Outgoing video communication requests are intercepted and screened by one or more unauthorized recipient lists, authorized recipient lists, caller-specific authorized/unauthorized recipient lists, and/or various combinations of these. The video communication requests may be blocked or forwarded to the recipient depending on whether the recipient is included or not included in one of the various lists. Third parties may also be prompted to accept or reject the video communication requests.
