My company have a new one Polycom HDX 9000. i have on issued with this, when setting IP Address manually in my polycom such as 167.205.x.x and click the next arrow so our system will auto restart. when this system on after that, our IP in my sistem back to 0.0.0.0 and always that when we tried to setting again. so I can't to tried call to other system because our IP Address always back 0.0.0.0 after restart.

So I need your guess and support about this problem. Thank You.
