What is an IPSLA device

Just to add to this, when we were running the trial, all we were interested in was the call data coming from the call managers so that we could monitor the number of incoming / outgoing calls and duration / ring time. We are not interested in latency or jitter or voice quality, so do we actually need an IPSLA devices to achieve this?

Can you post the Tier chart you are referring to?

Got it.

"Each monitored call manager or active Network Service Assurance device consumes a node license."

Ok, so you add nodes into VNQM similar to adding them to NPM. The node can be either a 'Network Service Assurance  device(IPSLA)' or a Call Manager so if you do not wish to use the IPSLA features then you can skip setting that up and add only Call Managers.

 Below will allow 50 IPSLA operations, 3000 phones and 400 Call Managers. If you do not wish to use IPSLA then you just need to ensure your call manager node and phone quantities match what you need to manager. Using IPSLA is optional and not needed to manage the call managers.

• SLA 50 – 50 Network Service Assurance sites, 3000 IP Phones, and 400 nodes

Perhaps discuss with sales before purchasing so you purchase the correct license.

Thanks for the explanation, we had pricing for all tiers, but our phones / call managers fall into the lower tier, we were just unsure as to wether we had or required any IPSLA devices for what we were wanting to achieve, and it doesn't look like we do.
