RTP statistics

About this task
The RTP statistics application collects data and statistics for RTP sessions (streams) from the
Branch Gateway VoIP engine. You can view the data and configure SNMP traps to be
generated when the QoS level falls below a configured level. RTP statistics support IPv4 and
IPv6 addresses.
Note:
An alternative tool available from Avaya for debugging QoS problems is VMON. VMON is
an RTCP QoS reports collector. VMON support, available in all Avaya devices, is the
capability of a VoIP device to send a copy of an RTCP message to the IP address of a VMON
server. VMON can collect RTCP reports, store them on its host hard disk, and analyze and
generate graphic reports. However, VMON requires a dedicated Windows server. The RTP
statistics application runs on the Branch Gateway's firmware, and does not require any
dedicated hardware. For information about configuring VMON in Avaya Aura
Communication Manager, see Administrator Guide for Avaya Aura
Manager.
Note:
The Branch Gateway performs traceroutes whenever RTP statistics is enabled.
The RTP statistics application provides the following functionality:
Procedure
1. Collects QoS data from the Branch Gateway VoIP engines, including Real-Time
2. Collects call data from the Branch Gateway, such as duration, start-time, and end-
3. Displays the RTP statistics in CLI and MIB formats
4. Displays summary reports for the VoIP engines
5. Assesses QoS status based on configurable thresholds on an extensive set of QoS
6. Generates QoS traps.

regarding jitter buffer, internal delays, and so on
Note:
RTCP is a standard QoS report companion protocol to RTP. RTP endpoints
periodically send RTCP report packets to their remote peer (or peers in multicast).
RTCP reports include QoS data such as delay, jitter, and loss.

QoS traps are notifications sent via SNMP upon termination of an RTP stream that
suffers from bad QoS. These notifications include extensive data about the session
