Convert a CP-6921 to standard SIP

[KenHenry0810]

I have a CP-6921 which I would like to use on standard SIP. Can I change the firmware & if so where would I download it from?

CP-6921 firmware can be found HERE.

Hi Leo, I can't download the firmware from that link

you need to have valid contract to download the software. if not associated with your ID  you cannot download it.
