Subject: RE: [Sip-implementors] why we need sip?
Hi Santosh,
..To add to what has been already written.... Ask yourself why
are HTTP
( WWW ) and SMTP ( email )so popular?
Well the same answers will answer your question as to why is
SIP so
popular and is the future of VoIP.
Here are the key points - SIP can exist anywhere along with IP and (
UDP/
TCP ). TCP/IP and UDP are is the protocols that drive internet
everywhere in the world. Hence SIP can exist anywhere in the world.
<Amith>
So is the case with H323. For your information, H323 is also just
another application layer protocol like SIP and uses TCP/IP for
transport.
</Amith>
All u need is internet. Its cheap compared to H.323 because it does not
require special hardware, it can be easily implemented and maintained in
pure software.
<Amith>
I don't agree with this. Even 323 does *not* need any special hardware ,
what hardware are you talking about ? Except a good , fast parser for
decoding ASN.1.And the stack would be a little more heavier than SIP
stacks.
</Amith>
SIP is just another "application level" protocol which is
end-to-end and hence scalable.
<Amith>
End to End , could you elaborate on this?
</Amith>
I'm not a h323 pro or something , but I don't think these make valid
points against H323 :).
best,
Amith
