Break-ups during data based calls after ten min

Please assist me in reporting this easily repreduced bug:

After ten min of voice call over Google-meet/WhatsApp I hear the other side breaking-up and they hear me breaking-up. After 30 sec the quality is restored. This happens again after 10 min.

Repreduced over various wifi connections, as well as over cellular network.

Today the break-up occoured when I receied an incoming message via the Signal app.

My question: How can I collect logs on the device to prove the problem?

Can I monitor the CPU usage to prove its not “choking”?

Device: Fp4

Build: FP4.SREL.15.14.4
