(3 out of 22 7941ip phones not registering with CUCM 8.6.1
I've got 3 phones that show up as "registered" in the CUCM but don't actually come up. I can't even reset the phone from the CUCM anymore. They have worked before but didn't come up after the CUCM was reset. Their screens do have the correct time and date but the rest is all blank. I have seen the "Authentication failed SCCP41.9-2-1S" several times. But its just really weird that it will show as Registered with the call manager but nothing on the phone itself changes. Has anyone else had this issue before?

the softkeys. You enable or disable them via TCL. Here is the long
answer. Be sure to read the whole thing or e...
