Under normal circumstances, that will always be true. There is, however, one caveat: If the connection between the bridge server and the venue server is broken, the bridge server will attempt to reconnect and, when it does, will allocate the ports anew.

In the next release of the toolkit, a range of ports can be specified for the bridge server to use for the venue server as a whole, or for individual venues. Thanks for the answer. So as long as the VenueServer is running with the BridgeServer and my rooms are bound to an IP and port, the unicast port won't change until I restart the Venue and Bridge servers?
