T4X phones reboot/hang randomly

[Jeremie]

Hi,

We have more approximately 30 phones, mainly T42G and one T46G.

Since a moment we encounter many reboot. The phone hang or just reboot himself, several times a day.

The phones are connected to POE ethernet cables and we have computers connected to the PC port of the phone, so the user lose internet connection every time the phone reboot.

The funny thing's one phone reboot, then another day it's another one or the same... Very random problem.

Also the phones are very laggy, slow...

Last firmware installed T42-29.81.0.25, static IP.

Thanks in advance for your help.

Best regards.
