I have a couple of GXP2170 phones I just deployed on Firmware 188.8.131.52. It seems to happen randomly when someone calls our ringgroup and hangs up on the first ring. The BLF’s get stuck blinking like phones are still ringing and the phone will not pickup or allow you to call out. The menus still work but ultimatly you have to reboot the phone to regain the ability to call. Just curious if anyone has seen the same thing.
Have had reports of similar on GXP2135 phones and UCM6202.
Probably we had the same issue with our GXP2170 (with firmware up to 184.108.40.206)
