Hey guys,
i recently bought a Cisco 7941 phone and i am now trying to upgrade the firmware to the SIP Protocol supported one. I already have a Cisco 7960 phone successfully set up, so I think my setup is working..
First of all, I downloaded a slightly older SCCP Version (SCCP41.8-0-4SR3AS) and reset the phone via 3491672850*# completely. This worked fine, the display is blank and the phone is looking for the firmware files via TFTP.
So I downloaded tfpt32, hook up the computer and phone to a switch, set the ethernet adapters ip to 192.168.1.1 / 255.255.255.0 static and ran tftp32.
I configured the DHCP exactly like this:
IP pool starting address: 192.168.1.2
Size of pool: 250
Boot File:
WINS/DNS Server: 0.0.0.0
Default router: 192.168.1.1
Mask: 255.255.255.0
Additional Option: 150 | 0x0101A8C0
The device tree of the tftp root Folder is like this:
Now, my Problem is, that the 7941 tries to catch up a TFTP Server from 0.101.8.1, instead of 192.168.1.1 as a conclusion that the tfpt Server receives no request at all and the phone can't find any firmware.
Screenshot from Wireshark:
As a conclusion: nothing is working - is there a mistake in my settings?
Thanks
Max
