You want to try different FW versions and see if that fixes the issue

Is this a single phone, or all phones on that model with that FW?

All IP phones in this version  7861(firmware sip78xx.11-0-1-11), Is done in a random way.

Are not simultaneous.

What HARDWARE version are your phones? There are known issues with slow behavior on rel 1 & 2 hardware which are not able to replicate on rel 3 and later hardware. I've never seen a formal document on this, but have spent months on TAC cases related to this behavior starting in 2014, and my TAC engineer was able to verify that this is a fact.

What is the TAC number?

When I restart the iPhone with this problem,
It works well

A quick restart will work but after 2-3 week, trouble came back...
