Does the JTAPI provider balance the load of device registrations across
all CTI Managers in a cluster?

Adam,

No, the load is not automatically balanced. When you add a devicepool,
you specify your primary and secondary CTI managers. (within your
cluster). When you add a device to a devicepool, it uses the CTI
managers configured for that devicepool.

Thanks,
Rajesh

We don't know for certain yet, but I ask this to be proactive. I suspect
this is going to be an issue for a current deployment which may need to
balance the load across 4 CTI managers. What repercussions would there
be to adding 4 CallManager clusters - one for each CTI manager - and
distributing the load manually until we can get a fix?

I'll go ahead and open a dev services case now to track.

Adam, Even though we do not support load balancing automatically from
cuaeadmin, with 2.5, it is very easy for the developer to get this
functionality since you have access to the management service api. You
can add the load balancing logic in your application and call the apis
to add the devices in the appropriate device pools. ah! the power of
management api....

Thanks,
Rajesh

Unfortunately, it has to be running in the next few days.

For the benefit of the group, the plan for a deployment like this is to
add all 4 CTI Managers in the one Telephony Server in CUAE. Then create
4 device pools each specifying a different CTI Manager as primary.

It would be nice if CUAE did this for you, but on the other hand maybe
not. In order to optimize the cluster performance, you want to ensure
that the device you're monitoring is on the same subscriber as the CTI
Manager you're registering to. This could be automated with the help of
AXL, but that might be a bit much to ask of the CUAE. As such, the plan
is to be prepared for manual load balancing.
