I'm using an MCU 4510 and I've configured built-in gatekeeper, and I have an issue that I can initiate call from endpoint to MCU but I can not do it vice versa,
the notification on MCU is " Local Gatekeeper Refuse the call", I check System Status on endpoint : H.323 "Registered".
then I disable Gatekeeper setting on MCU and change H.323 call from gatekeeper to direct, and I can make a succesful call form MCU to endpoint.
And I change mode again, it does not work correctly.
So , what can i do to fix the problem?
