We have 4 HDX 7000 units in our office and every morning we have to reboot the devices so they can make calls. It's not fallen out from the network because I can connect to it using the web interface without any problem but cannot make calls. It always says "Call has ended". I have turned off the screen saver as well. Replaced the switch which the devices are connect to. Also this happens during the day time. All the settings looks OK. As an example we make a call at 9am and around 12pm the system cannot dial out. So I have to login to the web interface and reboot the device or devices.

we had very similar issue.
Polycom replaces the unit to new one, but problem won't disappear., every morning HDX must be rebooted to make calls.
After few weeks of researching, we tried to disconnect LAN in the evening - Eureka! Just plug in cable and you can call. We were looking for problem in the network but with no results. Finally we turn on firewall and ban all incoming unknown IPs (there was a lot of SPAM calls till that). And the problem disappear. I don't know it is a system bug or network "tricks", but this workaround worked for us.
Support has seen many cases with similar symptoms and most cases are from robo calls or some sort of spam or hacks. In all cases the HDX systems were outside the firewall. We have also seen that frequent SNMP polls can cause the system to be very slow to respond and appear to be unresponsive.
