I am implementing UCM 7.0(2), with a 2821 Vgwy. I am wondering what the differences are in the MGCP versions. I have not been able to find a document that explains the differences. Does anyone have any insight on this?
I believe most people is going to tell you H323 is definitely not friendlier.
MGCP is mostly used because it's easier for anyone configuring this to have a setup in no time, any change you want is as easy as going to the GW or endpoint and changing it. Or choosing the new card on the GW and just doing the config on CUCM will create the dial-peers needed in the GW.
H323 is definitely more powerful than mGCP and has waaaaaay more features and functionality but does require more knowledge on how to configure it.
MGCP does most of the work for you, but all control falls on CUCMs shoulders and it loses flexibility on that.
