Biamp Tesira heads-up.
Just a quick heads-up for anyone working wit a Biamp Tesira. As of June 2016 the new firmware comes with a new feature. By default the Telnet IP port is turned off. You will need to go into the settings on the Tesira (via the software) and make sure to turn it on. Otherwise you'll spend an hour trying to figure out why your once working module is struggling... Up to this point, that port was open by default. After speaking with an engineer at Biamp, I would also keep an eye out for the possibility of the control port moving over to the SSH port.
