Yealink T58A sporadic restarts

[stefan.xp]

Hello,

we are using several Yealink T58A SIP-Phones which restart sporadically.
The issue occurs 1-2 times a week.
It occurs during idle-state and during use of the device.
We are using Firmware v58.86.0.20 and 3CX v18.0 (Build 461).
We have already replaced the client's PoE-Switch - with no success.
We have switched to static IPs and we have deactivated auto-provisioning - with no success.

Would be great if somebody can help me to solve that issue.

Try to update the firmware of your phone, this firmware ist pretty old.
