I have successfully registered my SIP endpoints (which we have developed) with Broadsoft sandbox environment. I can make basic calls without problems. When I try to conduct feature tests like Call Waiting (CW), Call Hold (CH), and Call Transfer (CT) the broadsoft directs my endpoint to send Invites off to a private IP (10.10.30.137). Refer to packets 56 & 66. This IP is not reachable so there's no response and the feature fails. Apparently we must setup a VPN to the Broadsoft sandbox environment in order to get this to work. My question is how do we get the ball rolling on getting VPN access in order to conduct the interop test required by our customer?
