What are most organizations buying today: H.320 or H.323 systems?
Most purchases today are for H.320 only or both H.320 and H.323. b) Today, there is a push for widespread adoption of H.323 as a video communications standard. This has particular appeal because IP (H.323) networks are believed to be far less costly to operate than switched digital communications (H.320) networks. However, cost are falling dramatically for switched digital calling around the globe, and because of important H.323 issues (such as firewall and bandwidth constraints) it is not certain that H.323 will become dominant. Instead, it is likely that H.320 and H.323 communications will both be used widely and gateways or gateway features will become standard in most networks.
