Google Trends information also confirms the popularity of this protocol.
SIP is a human-readable protocol, so SIP is simpler than H.323 when developing and supporting software. More scalable and flexible, easy to implement and adapt Less scalable and flexible, difficult to implement and adapt Let’s compare H.323 and SIP: Basis of Comparison Location Server – is a database of address information needed to provide personal mobility for users.Redirect Server – is a device that keeps a record of the current endpoints and proxy servers location in the network.Proxy Server – is a device that receives and processes requests from endpoints and performs corresponding actions within the network.User-Agent which consists of a User Agent Client (UAC) that sends SIP requests and a User Agent Server (UAS) that sends responses to such requests.Information is transmitted over IP (Internet Protocol). SIP (Session Initiation Protocol) is a technology that allows telephone network subscribers to communicate with each other, exchange multimedia, make video calls, and send messages. Gatekeepers – auxiliary devices that perform a number of additional functions, such as user authentication, endpoints registration, and communication.Gateway – the connecting path between networks or different standards endpoints that provides two-way communication.
AVAYA SIP DEFINITION SOFTWARE
Terminal – a device or software product that transmits multimedia data directly to the endpoint.The H.323 recommendation provides a variety of communication options: from voice telephony to full-fledged video conferencing, with the ability to send and transmit media streams. This is a set of protocols that enables point-to-point or point-to-multipoint media streams transmission over computer networks with unguaranteed bandwidth. H.323 is one of the oldest standards used for VoIP telephony and video conferencing. Thus, which one is better? Let’s find it out. Despite the apparently similar principle of operation, these protocols have become competitive due to gradual packet network expansion. The first was developed by IТU before SIP was released, while the second is recognized as the IЕTF standard. H.323 and SIP are the main IP signaling protocols for voice and video coding within corporate networks.
