The QoS for CallMan doesn't collect QoS data from switches.

It collects data about the calls it's putting through; jitter, packet errors, latency, stuff like that.

If your Gateway is H.323 all the calls that use that GW will be cataloge as NA since H.323

do not has the ability for QOS reports.

1. if the endpoint device does not support CMR data (packet loss, jitter, etc.) This

includes all h323 devices, some mgcp, and some sccp devices

2. if the call potentially matches multiple rules it may result in N/A:

If that is not our case make sure to enable the CMR records in the CCM Service Parameters, those records are the ones used for the QoS reports.

Unfortunately you won't be able to get QoS reports, there is no workaround on this one, H.323 just don't support CMR data.
