I have a 7940 which fails to boot up. it tries to load the files from the TFTP server but then throws up an error with Protocol Application invalid.
My set up is straight forward. I have a router with CME and DHCP configured. The Option 150 is set to an external TFTP server on the LAN.
AS the phone boots it loads 3 filesfrom the TFTP server; first it loads the XMLD default.cnf.xml file. then it loads P0030801SR02.loads. It then loads the same P0030801SR02.loads file again and then fails.
I tried the same with another phone and it loads the same files plus a final P0030801SR02.sb2
This 7940 will not load the final file.
Any help will be appreciated.
Thnaks for the response. I have managed to clear it. I loaded a higer level of SIP firmware then chnaged it back to SCCP and it worked a treat. Looks like the phone had SIP firmware which was locking down the phone. As soon as I managed to load the SIP it cleared the phone up and then allowed me to load SCCP.
