Hi List; In the h323.conf file, the parameter gatekeeper is used to let asterisk work as h323 gatekeeper listening at port 1719 by setting gatekeeper=DISCOVER or it is used to let asterisk search for the gatekeeper to talk with it and receive calls from it? But if just to let asterisk talk with it, then what asterisk will talk with it other than receiving calls from it? Any help?
