Hi
Our mitel 3300 mx is having issues and crashing intermittently. None of the phones can make out going calls or receive any calls. There is no dial tone on the phones either. On the LCD display of the phones there is a blinking cursor. Its as if the phones have lost connectivity to the controller. I can ping the 3300 but unable to logon by the web interface until you pull the power cable out or press the reset button. I've checked the programmed reboot display and is turned off. Current version is 8.0.9.20. This has been ongoing for atleast the last 6 months if not longer. We cannot put our finger on the issue and may not happen for months or so later.
I've searched the mitel software for know bugs and recently upgraded to 8.0.9.20 from 8.0.5.12
Modules are E1/T1, ASU and DSP.
Can someone check if this is a known issue with the mitel software backplane of the modules.
