Every office has a HDX system. I configure that VBP as a embbered gatekeeper, When i call from internet to our offices by dialling “VBP Public IP ## E.164”, call establish successfully. But when i call from intranet to internet (say Polycom test ip), call cannot establish. Please give me a solution.
