Question 1 -- you are correct. Gatekeeper functionality is for
distributed Call processing. Not needed in a centralized CM model.

Question 2 -- The gatekeeper is essential in distributed call
processing. I don't believe that a gatekeeper can replace a CM. There
is CM Express

Which does replace CM to a point. Its kind of a stripped down CM
running on IOS.

Subject: [cisco-voip] Call Manager and Gatekeeper

hi all,
I am a new to VoIP and have few questions on
functionalities of Gatekeeper and call manager

1. Is gatekeeper required only in a multi site
environment with distributed call processing
and
Not Required in single site or a multi site
environment with centralized call processing ? (is it
because all the call handling is done by call manager
it self ? )

2. Can a call manager replace the gatekeeper or vice
versa ? i.e in what deployment is gatekeeper essential
?

3. in a pratical deployment scenarios(large/ small)
does any one make use of the H323 Annnex G border
element congigurations available in Cisco IOS
