We are experiencing a strange issue affecting some Yealink handsets at some client sites.
Setup:
- all 3CX instances are 15.5
- all yealink handsets are running latest firmware and connecting using STUN.
- port redirection is in place for all handsets
The problem happens seemingly at random and causes some Yealink handsets to show "No Service". Rebooting the phone sometimes resolves the issue but in some cases we have to factory reset the device. When we check 3CX for the handset it shows registration failed.
This only affects one handset per client at a time, when it happened at a site this morning only one handset out of 30 were affected.
I am struggling to identify what is causing this, so would welcome any suggestions
