Why SIP is superiror than H.323? Hash007 16-November-2008 12:02:22 AMComments www.networkcomputing.com/netdesign/1109voip2.html Posted by crouse www.voipnow.org/protocols/h323 Posted by crouse www.tech-invite.com/SIP/3666/3666-2/Ti-SIP-3666-2.6.pdf Posted by saqlain231 H.323 is a family of H.32x defined by the ITU-T and it is more commonly used for multimedia application.Where as SIP is used for SIP = Short for Session Initiated Protocol, or Session Initiation Protocol, an application-layer control protocol; a signaling protocol for Internet Telephony. Posted by HamidAliKhan Despite SIP’s limitations, there are several often-cited reasons demonstrating why SIP is superior to H.323 in supporting IP telephony processes and applications. Emerging Dominance of IP H.323 is designed to be interoperable with other ITU-T standards in support of ISDN and ATM networks and includes all of the necessary mechanisms to support interoperability across multiple networks. SIP is designed primarily for IP networks, and the continuing growth of the Internet and its associated protocol makes interoperability a less important issue. Although the Internet has become a ubiquitous presence, the dominance of PSTN services for voice communications will continue for some time, making interoperability an issue for years to come. PSTN signaling interoperability and the more mature nature of H.323 are advantages over SIP at present. H.323 products currently far outnumber SIP offerings, although this is expected to change over time. From GlobalSpec.com Posted by sagitraz |
