Hello, I need help,
There is a problem with 7936, it cannot register by cucm7.0 server and station's LCD displays a message - "Cannot Contact TFTP Server". But 7936 receives right IP address and TFTP address and there is communication between them.
I run network sniffer and see a tftp communication between cucm and 7936, there is sequences downloading SEP-macaddress.cnf.xml and xmldefault.cnf.xml in that order every 15 seconds and no other traffic tcp or skinny only tftp.
It seems to me that 7936 doesnt understand configuration file.
It doesnt start upgrade firware also. Server cucm have newer version firmware.
After reset to defaults the problem persists.
Firmwire 7936(PC0503031518, 7936.3-3-2).
