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.

you have to use your cisco phone as SIP phone in the ipedge, and put username password provide from ipedge extension number, in the cisco phone

I don't know if your challenge will be connecting the phones tot he IPEdge, or just getting into the admin for the phones. From looking at Google it looks like Ring Central generally locks down the phone with an admin password, and there does not seem to be an easy way around this. It looks like some people have found a way to get the phone to load their own customer config file.

Unless Ring Central is willing to unlock these phones (unlikely)t looks like you could be in for a bit of work to get into the phone's programming. If you can get into the phone's admin, I believe that they should work as a regular SIP device on the IPEdge.
