Can Any one point out some advantages of SIP
The unique advantage of SIP is IMHO the integration of all types of
communications, not only voice and video, that H.323 does too, though far
too much weighted down by it's ISDN heritage.
Instant messaging and presence may be one of the key new services and you
may have noticed that many IM systems (for example Microsoft Windows
Messenger based on SIP, SIPquest, HotSIP, other) also offer voice and video
as an option, so you use them only when appropriate. Actually, presence may
turn out to be the dial tone of the 21st century.
Add to this SIP mobility and integration of communications with applications
based on the SIP events architecture and it seems quite clear that H.323 is
not even in the same class as SIP.

Subject: [Sipforum-discussion] Why SIP??
Hi all,
Can Any one point out some advantages of SIP, that why we need SIP in
application like Video Conferencing, which we can't get without it. Though
some of them I think are,
1. To make a consensus between the the user of application/system, over the
characteristic of media to be used in conference.
2. Call making would be transparent, like either caller or callee can be a
Desktop application, IP telephone, PSTN user etc.
3. Maintains state about session being establish for some features like
billing etc.
4. Locating prospective session participants.
Can any body add some more features, or make any comments. Any effort will
be appriciated.
Rajat
