CUCM - DNA feature enable

[S N]

Hello All,

For some reasons, the customer has disabled the Dialed number analyzer feature in CUCM.

They need to enable it now and just wanted to ask you whether enabling DNA feature will impact anything in CUCM.

Thanks

Hi Sathya,

No, it doesn't impact anything when you enable DNA.

Hi,

Thanks for your comment. One more clarification needed , is it to be enabled on all the servers in the cluster or only in the publisher.

Thanks

enable it on all the servers.

Thanks again, but still confused.

Jamie , DNA is just for checking the configuration is correct and the call is taking the proper route.

Any idea why it consumes larger resources.

Is it not a recommended one by cisco for enabling on the cluster ?

Thanks again

Hi Sathya,

As mentioned by Jamie and others, DNA can be enabled on any one server in the cluster most probably the Publisher (where lesser number of or no endpoints will be registered).

It uses resources as it needs to contact the DB for all the queries and show you the actual call routing based on the configuration but you can safely enable it as it will not affect that huge. However if you still have concerns, you can enable it whenever needed and disable after checking.

HTH,

Thankyou all.

I will enable it only on Publisher during low peak hours and will let you know if any issues.

Thanks all for your help

Cisco Dialed Number Analyzer

The Cisco Dialed Number Analyzer service supports Cisco Unified Communications Manager Dialed Number Analyzer. When activated, this application consumes a lot of resources, so activate this service only during off-peak hours when minimal call-processing interruptions may occur.

Cisco Unified Communications Manager clusters only: Cisco does not recommend that you activate the service on all the servers in a cluster. Cisco recommends that you activate this service only on one of the servers of a cluster where call-processing activity is the least.

Cisco Dialed Number Analyzer Server

The Cisco Dialed Number Analyzer Server service along with The Cisco Dialed Number Analyzer service supports Cisco Unified Communications Manager Dialed Number Analyzer. This service needs to be activated only on the node that is dedicated specifically for the Cisco Dialed Number Analyzer service.

there should not be an issue, since the DNA uses call manager's DB for any call analysis performed and displays the result.

just need to make sure that the DB is in synchronization with cucm's db, which happens on enabling the DNA.
