[SIPForum-discussion] doubt regradinng SIP and MGCP

[Naresh Parmar]

SIP, H.323 and MGCP, all these three are the signaling protocols which
can be used to provide multimedia signaling capabilities. MGCP is a
protocol in which the the end terminals are dumb and they just notify
the controller about the events (i.e. like phone offhook), the
controller then instructs the terminal to do further processing(i.e.
like providing dial tone etc).. the whole brain is in the controller.
This may be useful in situations where the endusers do not want to buy
expensive equipment and are good with their dumb terminals.

H.323 has been the most widespread signaling protocol out there today
and provides seamless integration with the traditional PSTN networks.
SIP is increasingly becoming popular and will eventually be the winner
because of its simplicity and flexibility. SIP provides better user
mobility, integration with the other services like DNS, ldap, database
services, multiple contacts for a given user and a lot of flexibility
to write applications around it. H.323 has some advantages over SIP in
terms of PSTN integration and more resemblance to the traditional
circuit switched systems.

Finally, SIP can be integrated with the PSTN or going further it may
replace the traditional phone system as such simply because of the
flexibilty provided by SIP wherein users would like to have
fascinating features added to their phone devices.

Hope this clarifies some of your doubts.
