I tried to upgrade a Cisco 7970 to Sip 8.0.3 from the default firmware. Following some advice I factory reset the phone first. Upon reboot the phone does see the tftp server (using solarwinds tftp) and starts to download the firmware files in the following order:
term70.default.loads
jar70sip.8-0–2-25.sbn
cnu70.3-1-2-26.sbn
apps70.1-2-26.sbn
It fails on the apps.xxxx.sbn at 81% complete. I ran a packet sniffer and the phone seems to indicate a write error (any ideas???)
Anyone have any suggestions? I was thinking that because I did a factory reset it is looking for a sccp load and is getting screwed up b/c I’ve got a sip firmware in the tftp server. Thoughts???
