ok in brief
h323 need a full dial-plan configured on it for example for simple voip network with callmanger u need at leat on pots dial-peer to recieve and send calls to pstn and one voip dial-peer to recieve and send calls to callmanager
this is simplest way
however in my openion i see with h323 u can have more control over calls like u can use trnaslation profiles in conjunction with callmanger translation pattren they could work to gather or u have the translation only on ur gateway
an IMPRTANT thing that if u wanna reject a call or match a call based on calling number with h323 u can do it with mgcp and callmanger u CAN NOT !!!
if u look to have a SIP trunk in future h323 will be the best for this solusion
MGCP helpful when u have many gateways and u need the managment of these gateways to be centralized thorugh the callmanger
also mgcp use callmanger dial-plan only u dont need to configure and dial-peer on it
this is in brief
if u have small number of gateways i would suggest u to use h323
good luck
if helpful rate
