I have a prospect using a hosted system from Ring Central they have around 40 SPA942 handsets. The call quality is not to good and they are wanting to get away from a hosted solution. Since they own the handsets they are asking me to try to reuse them.My question is has anyone had any success using the Cisco SPA942 phones on a Toshiba IPEdge, and, does anyone have firmware/cfg files for those phones. I wouldn't be suprised if ring central has installed custom firmware on the phones.
