[cisco-voip] Unified Presence (CUP) and the CUCM hostname/IP address

[Philip Walenta]

CUCM changed also without issue.  Application server settings were changed.

 
Forward and reverse are correct.
 
It just wants to hang on to the old IP address no matter what I do.  I'm
trying to avoid a complete rebuild :-)

If you are using DNS, make sure you update the forward AND reverse lookup
zones for CUP. Also, check under the System - Application Servers section in
CUCM Admin too and make sure the CUP server is still properly defined.

 

Did CUCM's IP change as well?

What version of CUP is it? CUP 6.X didn't support changing the IP. You would
need to rebuild it instead. CUP 7.X does support changing the IP however.

Due to some lab conditions I'm having to change the IP addresses of devices
(ugly - I know).

 

My one stumbling block is that when I tell my CUP server the new IP address
of the CUCM publisher it complains about the hostname being incorrect.

 

If I goto my CUP CLI and do a network utils ping <hostname>, the old IP
address resolves.

 

Is there some hidden hosts file on the CUP server doing this resolution?  My
DNS server is correct.

 

If there is a hosts file is there some way to change it or force a rebuild?
