If you require support for your H.323 equipment, simply select it from the protocols available when you create your account. If you already have an account, and would like to add an H.323 gateway, please open a ticket with our support team. We have confirmed operability with all the major H.323 gateway vendors, and can allow your legacy H.323 VoIP installation to take advantage of the newer SIP carrier implementations. Although many greenfield service providers and equipment makers now choose the SIP VoIP protocol,we recognize that many of the earlier VoIP implementations are still actively relying on H.323. After all, why mess with something that works. As a result we fully support H.323 origination. |

H.323 is a specification from the ITU defining a standard way to provide audio-visual communication sessions on any packet network. The H.323 standard addresses call signaling and control, multimedia transport and control, and bandwidth control for point-to-point and multi-point conferences. It was the first VoIP protocol to be widely implemented by voice and videoconferencing equipment manufacturers, is used within various Internet real-time applications such as GnuGK and NetMeeting and is widely deployed worldwide by service providers and enterprises for both voice and video services over Internet Protocol (IP) networks. It is a part of the ITU-T H.32x series of protocols, which also address multimedia communications over Integrated Services Digital Network (ISDN), Public Switched Telephone Network (PSTN) or Signaling System 7 (SS7), and 3G mobile networks.
