ABSTRACT:
For quick call setup, terminal A sends to terminal B stuffing sequences for the highest H.223 multiplexer level supported by terminal A and at least one proprietary sequence. The proprietary sequence indicates support for quick call setup and contains video and audio codecs supported by terminal A. Terminal A monitors for stuffing and proprietary sequences sent by terminal B. If terminal A receives a proprietary sequence from terminal B, then terminal A sends an H.245 NonStandard request message containing the information in the proprietary sequence sent to terminal B, video and/or audio capabilities supported by terminal A, and entries for a multiplex table used by terminal A. Terminal A monitors for a NonStandard request message from terminal B, which contains video and audio capabilities and multiplex table entries for terminal B. Terminals A and B are ready to communicate upon each terminal receiving an acknowledgment from the other terminal.
