I am trying to set up SLB on a 6509 switch to load balance phone services 
on a CMv6.1.3 pub/sub cluster and cant find a good doc on what 
configuration steps to take, these documents, give brief guidelines:


1) I applied the following config to my 6509 switch and can now ping the 

ip slb serverfarm CCMV6
ip slb vserver CCMSLB
 virtual real tcp 8080
 serverfarm CCMV6
 inservice standby VOICE-HSRP
interface Vlan101
 ip address
 standby 1 ip
 standby 1 timers 5 15
 standby 1 priority 105
 standby 1 preempt
 standby 1 name VOICE-HSRP

2) I changed the CMv6 Enterprise parameters to the new vip and restarted 
the "Cisco CallManager Cisco IP Phone Services" on both servers and 
restarted the phone, then tried to access the phone services and 
nothing... (phone services working well without using the vip)

Any ideas?
