Hello,
I have two SPA525G2 on the same location who start to have the same problem since a couple of months: When the sound comming out from the speakerphone is to loud or too actute, the phone reboot. It's may come from a ringtone or during a call on speaker phone. Any idea from where it's may come ?
I already tried to upgrade to latest firmware (7.6.2) and factory reset a phone to test without success
