I have new Cisco IP Phone 7941, I have configured on my cisco 2851, CME 4.1.
But on router I have firmware on flash SCCP41.8-2-2SR1S not 8-2-1S. The phone didn't upgrading with this firmware, and reboot every time and searching firmware 8-2-1S.
Normally router decide which firmware to upgrading phone, but not in this case.
See log (console on phone) and picture (bad quality) in attachment, if you have any idea, thanks.
