Abstract
A technique for merging conference session dialogs allows presenting content and media streams from a non-Skype endpoint to a Skype multipoint control unit (MCU), so that they present a single caller in a conference with both media and content. A signaling adapter intercepts session dialogs and merges or other modifies. When adding the non-Skype endpoint, requests from a content server are dropped while requests from the MCU handling non-Skype media streams are forwarded to the Skype MCU. Responses to the request from the MCU are also forwarded to the content server. When creating subscription dialogs, requests from the content server are modified to appear as if they came from the MCU, while responses go back to the proper requester. Conference notifications are forked to go to both the content server and the MCU. Because Skype uses separate media and content dialogs, merging of audio/video and content dialogs may be omitted. By merging dialogs, user experience is improved.
