We did resolve this issue. The phones do reboot sometimes, but that could be something else on the network. The main resolution that fixed this for us was VLANning. We were in on large broadcast domain. While we cant technically confirm this was the issue as I had network experts indicating that the phones should be able to handle this, they could not. We split the entire network up into 12 different vlans and have the phones in one of their own. The phones have not acted as before since 2013. They are stable. Let me know if you have any questions.

This is an old thread, but I'll throw my 2 cents in just in case someone else has an Iwatsu reboot issue..

We had a big reboot problem after upgrading to Ver 12 to get the receptionist console capabilities.

After going through and tearing out every network monitoring device i had (SNMP apparently makes these things reboot), we installed VLANS for network endpoints, workstations, phones, cameras etc. (apparently, excessive broadcasts make these things reboot). We ran new cat6 to each desk for a dedicated phone connection (apparently too much traffic from a tethered workstation will make these things reboot).

Long story short, I went through the network and took care of all of the things that the Iwatsu engineers said would make these things reboot,

Our problem ended up being some strange network issue that was solved by a switch reboot and a full phone system reboot. All of the IWATSU phones were flapping ports on a cisco switch trunk in one of the connected buildings. After a reboot, they got their act together and we've had no more phone reboots.
