Cisco IP Phone 7912G

Important! Information available at this page is not correct. This phone in fact does support 802.3af Power Over Ethernet, i have tested it. Maybe it does support also cisco pre-standard because there is a diode bridge that allows reverse polarity powering over rj45.

Version of the previous firmware CP7912010300SCCP…..?

Version of the upgrade firmware CP7912010300SIP050414A

Just put the following files in the tftp server root directory:
