Hi,

Have a 12 node Netlink environment. Main site is CP-20 Ver 12.0.0.50 sites 2-10 CP-10 Ver A12.0.0.50 sites 11-12 CP-20 Ver12.0.0.50. Sites 11 and 12 were recently added hence the CP-20's upgraded to Ver 12 beginning of February and have had the system lock up 3 times. No LAN response at all. have to reboot the main site to reset LAN and have SIP trunks and all nodes reconnect. looking to see if anyone has had this happen and has some insight as to why it keeps happen. or if NEC will look into and release an update to VER 12!

Thanks!!
