Avaya VoIP Monitoring Manager Reference

Q
QoS: Refer to Quality of Service.
Quality of Service: QoS is the measure of the level of quality that a service requires or receives.
The VoIP Monitoring Manager monitors and displays the 3 main factors that determine
the quality of VoIP calls. These factors are Jitter, Round Trip Time, and Packet Loss. On
the Summary Report each of the three factors display as a separate gauge.
R
RcvrIPAddr: The RcvrIPAddr column displays the IP address of this session participant (i.e.
endpoint). This column appears in the Session Table of the exported file.
RcvrPHONE: The RcvrIPAddr column displays the phone number of the participant. This column
appears in the Session Table of the exported file.
Real-Time Transport Control Protocol: A protocol providing support for applications with real-
time properties, including timing reconstruction, loss detection, security, and content
identification. It reports information about the RTP stream.
Real-Time Transport Protocol: Real-Time Transport Protocol is the protocol used for
transmitting real-time data. For more information see IETF RFC 1889 located at:
http://www.ietf.org/rfc/rfc1889.txt
Resource ReSerVation Protocol: RSVP is a protocol for reserving network bandwidth on the
routers and switches between two endpoints in a session (in some other protocol, such
as RTP). There are two reservations per session, one for each direction the data has to
travel. For further reference see the IETF RFCs 2205 and 2750 located at:
http://www.ietf.org/rfc/rfc2205.txt and http://www.ietf.org/rfc/rfc2750.txt
Round Trip Time: Round trip time is the length of time (in milliseconds) it takes a packet to
traverse the network and return (thus being a round trip). It is the sum of the two one-way
network delays between two endpoints. Callers can experience difficulties in carrying on
a normal conversation when the one-way network delay exceeds 500 milliseconds (ms).
However, some users may elect to tolerate this.
RSVP: Refer to Resource ReSerVation Protocol.
RSVP Status: The RSVP status for an endpoint shows whether the RSVP is enabled on the
endpoint, and if it is, whether a reservation was established for the received RTP data
stream.
RTCP: Refer to Real-Time Transport Control Protocol.
RTCP Listen Port: The RTCP Listen Port is the configurable port that is used to collect RTCP
information from the AVAYA endpoints. The number must be from 1025 through 65535.
The default port is 5005. Users are advised to avoid choosing ports in the reserved and
'well-known' ranges.
RTP: Refer to Real-Time Transport Protocol.
RTP MIB: The RTP MIB stores the information for the active RTP Sessions. The reference for the
definition of the RTP MIB is located at: http://www.ietf.org/rfc/rfc2959.txt
RTP Session: A session is a VoIP connection between two IP endpoints. For more information
see RFC 1889 located at: http://www.ietf.org/rfc/rfc1889.txt
RTT: Refer to Round Trip Time.
