I have now had my second SPA-3000 fail in less than 6 months.
It absolutely refuses to recognize any key-presses on the telephone on the Phone port. This leaves me with no way to get to the IVR or reset the unit. It also leaves me with no way to dial-out using the attached phone.
I've verified the cables, powered-off and powered-on, reflashed the firmware, and downloaded back-up configurations several times over the past few days and still nothing.
The web interface works just fine but still leaves me with no way to reset the unit.
Anyone have any ideas before I send this replacement back too?
