I'm installing an IPPBX at our office, using some new hardware, but also using an SPA921 we bought a some time ago (feb 2008).
The phone has never been really used, except for some testing at the time of purchase...
Now I'm trying to set it up, but the phone reponds erratically; when picking up a line, it hangs up immediately, the 4 keyboard buttons at the botton of the screen do not match the text displayed on the screen (if I press dnd button, cfwd highlights; if I press dir button, redial highlights). Also, when typing a number, the phone goes crazy and types continuously numbers on the screen).
I even tried to downgrade it to a previous firmware, but same results.
Any clue ? Is that kind of hardware still under warranty ?
In the meantime we purchased a SPA504G for testing purpose, but of course we'd like the SPA921 to get fixed.
