I recently acquired 4 new-in-box M5209s, with the hopes of connecting them to my existing Compact ICS system. It appears that they do not work.I have also tried plugging them in to the analog fax line through the included power adapter, but again, no luck. Is there a way to make them work?
Also, what models of phone _will_ work on my system? The system came with some T7308s, but I would like to shop for whatever will work with the CICS, ie, the phones don't have to match.
