Symptom: SPA525G: Phone lockup with 'Ringing' on LCD display Conditions: SPA525G running 7.5.5 / SIP 1. Enable STUN on UUT. (<STUN Enable > = Yes, <STUN Server> = x.x.x.x,< NAT Mapping Enable > = Yes) 2. RU1 calls RU2 and connect the call. 3. RU2 holds RU1 and call UUT. 4. UUT answers the call. 5. RU2 transfers RU1 to UUT. 6. End the call between RU1 and UUT. UUT is in idle status. 7. Make a new call on UUT. Result: If SPA525G is UUT, it will always display 'Ringing'. An outbound call cannot be made anymore, and we need to power cycle or receive an incoming call to make the phone come back to normal status.
