[cisco-voip] Trouble Getting 8831 to register

[carlo_calabrese2006 at yahoo.com]

I was also having problems with the 8831 on a 10.5. 
I found that if I had the tech do a factory reset from the menu, the phone would come up. Another problem was with the database. I would have to delete the phone from the system and let the phone auto register.

The strange thing is that I found that the registration is "Rejected" before I even patch the phone into the network.  TAC updated the load information for the 8831 to sip8831.9-3-3-TO-10-3-1 so I think I have the most up-to-date load for the phone.  I am using a switch port that had a 7965 attached to it so I know the pathway to CUCM is clear.  This is the first sip phone we have tried to introduce to the system but we have sip trunks so I know the correct ports are enabled for sip.
