[cisco-voip] Cisco Unified Communications Manager 6 Failover

[Adam Frankel]

Cem,

 

You need to configure the Device Pool assigned to the device to have a
Callmanager group that includes the primary and secondary device.  Once the
phone is up check the phone web page to see what server is its current
Active and Standby CUCM. 

 

HINT:  If the servers are listed under System->Server as DNS/Hostname the
phones needs to be able to resolve these successfully otherwise they will
end up being registered to their TFTP server only.    If you cannot
implement name resolution, try changing these values to IP addresses.

Hi guys,

I'm desperate on this.. We have a 3845 voice gateway attached to two 7800
series call manager servers. Here is the deal; i would like to integrate
failover feature within these two 7800. I've searched all over the cisco
documentations but no use...

We already have an operating CUCM 6, besides yesterday i could manage to
setup second node. I can see the second node in CUCM 6 as subscriber in the
cluster. But when i pull out the first node's LAN cable, second one does not
automatically takes place as the first node and make a failover. All the ip
phones stuck, while trying to obtain IP address. Besides, when i give the ip
address (which was obtained when the first node is online) manually, the
result is the same, phones stuck. 

As i said, i couldn't find any detailed documentation how to make an
operating failover, the ones that i found was not enough for me to do the
job.

I am waiting for you guys to help on me.

Kind Regards.
