Q. Why am I having trouble neighboring my TANDBERG VCS with the TANDBERG Codian built-in gatekeeper?
A. A very few devices such as the TANDBERG VCS send an endpoint identifier element in the LRQ. Prior to the Codian MCU version 2.3, the built-in gatekeeper checked this endpoint identifier element, and thinking the device was an endpoint, rejected the request if the identifier was not registered.
From MCU version 2.3(1.0) onwards that check is no longer performed. If you are having difficulty neighboring to a built-in gatekeeper on a Codian MCU, upgrade the MCU to the latest version which is available on the web site.
