NetMRI can collect CDR and RTCP data from Avaya Call Servers and endpoints for the
purpose of gathering call statistics and monitoring quality of service.

System administrators can selectively indicate which Avaya Call Server should be
allowed to send CDR data to NetMRI. Each Avaya Call Server must be configured to
send CDR data to NetMRI. For all such servers, NetMRI listens for CDR data on TCP
port 9000. CDR data is combined with similar data from other VoIP servers, including
Cisco CallManagers, to generate the VoIP summary displays provided by NetMRI.
Collection of CDR data is optional.

NetMRI automatically listens for RTCP data (e.g., latency, jitter and packet loss) on UDP
port 5005 from each Avaya VoIP endpoint as soon as they are discovered by NetMRI.
The Avaya VoIP endpoint must be configured to send RTCP to NetMRI. RTCP data is
combined with call performance data from other sources to generate the VoIP
performance displays provided by NetMRI.

Avaya only allows one RTCP monitor to be configured per endpoint. To allow other
RTCP monitoring packages to work with NetMRI, NetMRI can be configured to forward
collected RTCP data to a second location. This is done in the Settings > VoIP section >
Configuration page. In that page, enter the IP address of the desired RTCP monitor.
When NetMRI receives RTCP packets from Avaya endpoints, it will then forward those
packets to the specified endpoint.
