most likely there is error in your search rules but at this stage is hard to say. you need to enable debug mode on VCS and collect logs to see where the call gets branched to.

As you only write "vcs control", in most enviroments you will need a vcs espressway to

be able to handle external calls. At least if not all systems and the vcs-c would be reachalbe

transparent from the remote site which would require no NAT and a huge range of ports to be opened.

Besides that, no video alsways smells like firewall issues.
