[cisco-voip] live updates on subscriber - anyone tried it?

[Wes Sisk]

Stop CTIManager as well - it actually has a default hook into the  
local ccm.exe.  If you have an CTI apps using CTIManager this will  
force them to roll over to another CTI Manager and avoid a 2nd  
interruption.

Yes.  CSCea71523
Symptom:
	The actual function MaxStationsInitPerSecond parameter is somewhat
	misleading - has nothing to do with "time".

Condition:
	Normal operation.

Workaround:
	None, but request this parameter be renamed to something like:

	MaxPhonesFallbackQueueDepth


Online Help Suggestion:

	The maximum number of phone registrations a
	higher order CallManager queues at one time.

	When a phone determines that a higher-priority
	CallManager is available, it sends a registration
	request.  Once acknowledged, the phone will
	immediately unregister on the lower-priority
	CallManager and a registration request is placed
	in the queue of the higher-priority CallManager.

	A phone is unregistered for the amount of time
	it takes the higher-priority CallManager to
	process the queued registration request.

Furhter: This service parameter defines the number of signals
that StationInit process can handle at a particular time slice. So it  
not only controls
registration requests it will also control things like number of  
simultaneous
offhooks that may recevied by the CallManager.

Just wondering if anyone has tried updating the O/S on a subscriber  
during business hours, obviously after stopping the CallManager  
service and forcing phones to register to another subscriber first.  
Our goal is to try an minimize the amount of after hours work that is  
involved in maintaining this new fancy system of ours.

Ideally, we'd see the following happening:
stop callmanager services and have phones register to another  
subscriber during a short maintenance window
update O/S during the day
start callmanager services during a short maintenance window
Some questions:
are there any other services we should stop to make this as  
transparent as possible?
does the Maximum Phone Fallback Queue Depth service parameter help in  
any way in getting phones to register quicker on the next callmanager  
in line?
Any comments would be extremely welcome.
