Abstract: SIP INVITE messages received at a load balancer are returned as SIP Redirect messages which are addressed to an access director and include additional information, such as a tracing token and a cryptographic token. When the access director receives the redirected SIP INVITE, the access director analyzes the included cryptographic token and passes the SIP INVITE if the cryptographic token is correct. This provides the needed access control function to allow the access directors to be directly accessed by the endpoints, rather than funneling all communications through the load balancer.

Abstract: A non-Skype multipoint control unit (MCU) is configured to operate differently for handling incoming streams from endpoints and outgoing streams from a Skype multipoint control unit. When passing incoming streams from non-Skype endpoints to a Skype conference, the non-Skype MCU acts as a gateway, passing the streams to Skype MCU as if they were coming from Skype endpoints. When receiving outgoing streams from Skype MCU, the non-Skype MCU acts as an MCU, transcoding, compositing, and scaling streams into continuous presence layouts for delivery to the non-Skype endpoints. Thus, non-Skype endpoints can participate in Skype conferences as if they were Skype endpoints, allowing a better user experience for both Skype endpoints and non-Skype endpoints.
