The issue may be Opera related. What kind of console is being used at the hotel? I assume a 5540 IP console? If so, open a telnet session to 6830. Next, manually check in a vacant guest room. Call that room extension and leave a voice message. You could also just set a wake up call for that room extension via the console. Check your telnet session to see if there's communication from port 6830. If so, Embedded VM is working as it should. Reach out to Opera for answers.
