Cisco 7945 Issue - Need Input from Firmware Experts
I have some Cisco 7945 IP Phones that were previously imaged with SIP for some testing in our lab. I performed a factory reset procedure on them, intending to convert them back to SCCP, and now I cannot get any of them to respond.
I have the Cisco cable that allows me to connect to the phone’s auxiliary port and watch it as it boots. I was able to hard reset 2 phones and get them to take SCCP files, but there are phones that continuously give CDP errors and show no port activity (no link). I have tried 2 different DHCP/TFTP servers (TFTP32D32 and Windows 20003 Server w/ DHCP).
I even hard code the IP using the phone’s RS232 port and point it directly at whatever tftp server I currently have running. When I run ethereal, there is absolutely zero activity from the phone – no broadcast or request for DHCP reaches the network. On the phones that will not load (stuck at upgrading screen), the phone’s internal ios doesn’t show any firmware – SIP or SCCP- loaded. I can see the SCCP firmware as well as SIP firmware on my test phones.
Wondered if anyone has experienced something similar with the 7945G and may point to a fix? Thanks in advance!
