[cisco-voip] Cluster setup with 2 Subs - Sub 2 did not pick up the load.

[Bernhard Albler]

Gary,
You mention TFTP List: Do you mean the TFTP as assigned from DHCP (Option
150) or the CallManager Group in UCM?
Registration Failover is exclusively controlled by the callmanager group
This should work, check
1.)Callmanager group assignment in UCM
2.)Do the phones pick up the config (Check phone log for tftp errors)
3.)Check phone config via the phone web page (do you see all call control
hosts assigned there)
