[cisco-voip] IPCX Login if Publisher is down

[Baumgartner, Matthew]

Hi All,

 

I have a question regarding IPCC and CCM Split Clustering...

 

*         CCM 4.2(3) sr2b

*         IPCC 4.0(5) Build 042 

 

In IPCC version 4.X can Agents login when the publisher is not
available?

 

The below is and excerpt from the IPCC 3.5 SRND and it clearly states
that this is not possible. 

However I can't seem to find clarification if this was fixed in IPCC
version 4 or not.

 

 

>From the IPCC SRND page 37:

 

If the failed Cisco CallManager is the DCD server authenticating the
IPCC Express (the Directory Host Name defined in IPCC Express
Configuration and Repository, Directory Setup parameters), there is no
IP application redundancy because the failure of a Cisco CallManager
hosting DCD is a single point of failure for IP IPCC Express. The
following behaviour can occur:

 

*         LDAP authentication errors will occur in IPCC Express
Application Administration. 

*         All incoming calls to the IPCC Express route point will return
reorder tone (fast busy). 

*         Agents will not be able to log in again. 

 

For this reason, the subscriber server should be configured as the
primary CTIM and Cisco CallManager.

An option for reducing the downtime is to install a DCD on a standalone
Cisco CallManager server in the cluster or on an external corporate
directory server.

 

 

Any help would be greatly appreciated...

 

Thanks,
