Yealink Phones are unregistered in a random way for exactly 24 hours

[jonathanv]

What about Security > Trusted Certicates > " Only Accept Trusted Certificates " in the Yealink's web interface, should they be enabled ?
Actually for the five T42s it's enabled but not for the 2 W60B DECT Base.

Nope we just changed setting on 3cx server, not on phones directly

Many thanks Jonathan for your helps.
I will continue searching next time when the issue occurs again.
But I still not understang why it was working fine for 15 days before being unregistered.

Shall I launch the pcap feature for 5 min on all the phones or only one is sufficient ?
And how to read a .pcap log after exporting the file ?

Since the issue happens to all phones the behaviour should be the same. So only one phone will be fine.
Once you have the files send me a p.m. and we can look at the captures together.
