Does anyone know if any ports need to be opened up to manage the callflows on a UCM over a WAN? I know that port 7070 needs to be open to manage the actual server, but wasn't sure if anything needed to be done to use VMPro client. I have a customer with multiple sites (UCM at each site) and I'm trying to set up a single remote access server to manage all sites, but when I try to log in via the VMPro client using Administrator/Administrator and the IP address of the UCM, I get "Failed to create remoting interface".
