H.323 Continues to Lead Videoconferencing Revolution
February 19, 2010
H.323 and SIP were both created in the later 1990s to more-or-less address the same market: to enable one to place a voice or video call over an IP network. H.323 benefited from borrowing a lot of concepts from previous-generation multimedia systems, giving it the ability to easily handle voice and video conferences that might be as small as two people or as large as hundreds of people. SIP took a different direction and it seen an extremely slow road to adoption.
