cisco 7921g instalation

[PETERWARB]

Dear Community

I've got for phones and want them to integrate in my existing System. At first I'm looking for a usb driver for Windows 10. Second is there a Firmware with Sip Support? And third is there any possibility to get the management Software for private Person?

Thats at first all.

Thank you so much and a happy New year

That phone model is past the eol/eos, software for devices past that point is removed from the downloads site at Cisco. You required a valid support contract to download it, and there was no SIP FW for the device, it's SCCP only.

Right now Google is your best resource to try to find any download for that device.

7921G USB drivers are the same ones used on the 7925G. 
The USB drivers can be found HERE.

NOTE:  There are no "Windows 10" drivers available for this model of phone.
