Random ip6920 handset reboots

[bilbotel]

Hello, we replaced all of our ip5224 handsets with 6920's. I have noticed that every now and then some of them seem to randomly reboot. How can I find out why this is? Is it something to do with the Mitel O/S not being fully upto date? There about 30 phones.



    Release level: 8.0 SP2
    Active software load: 14.0.2.26
    Inactive software load:
    System relink: No relink has been applied.
    Call Control relink: No relink has been applied.
    Platform: MXe-III
    1024MB of RAM

Might just be the 6900 set firmware, the early versions were very buggy. There's a procedure to update just the set firmware, but frankly I'd go ahead and update the entire system if possible as MiVB 8.0 is either out of support or about to be.

Switch, Cisco Meraki MS225

Will updating the 3300 to v10 then push out a fw update to all of the handsets?

You can check the switch and see if that tells you anything interesting.

Yes, an update to the MiVB will include updated phone firmware and the phones will download and apply the new firmware. I don't recall if you need to reboot the 6900's or if they automatically check and update.

Nothing on the switch so far, at least in terms of Poe.

Will keep digging and chase vendor of O/S update in the meantime. Thank you

That's certainly possible. I'm assuming MAC 08:00:0f:b7:56:**/IP 192.168.1.2 is the controller? What's the source device from that log message?
