[cisco-voip] IP Phone Keep Looking old CCM

[Ryan Ratliff]

Sounds like you are talking about the OS Admin hostname of the server  
versus the CCMAdmin System->Server settings.   The OS admin pages are  
all specific to the OS of the server.  The CCMAdmin settings are all  
the CallManager application settings.   They are entirely separate  
and only related in that the CUCM application relies on the  
underlying OS.

IIRC  you mentioned before that you do not have DNS configured in the  
network.  If that is the case and your System->Server entries were by  
hostname then you are lucky your phones registered in the first  
place.   I encourage you to go check the documentation for more  
information on the role the System->Server entries play in phone  
registration.

I have just changed the name from system->server to IP and kept the  
hostname in the field of the hostname of the settingd->ethernet- and  
the phones overcame the problem and work fine!
If someone could explain this?
If you have an ip configured in system->server what is the meaning of  
host field in the settings->ip-?ethernet field?

Thanks and Kind Regards
