Description: Monitors RTP media stream quality metrics including jitter, packet loss, and MOS scores on Avaya VoIP platforms.
Start monitoring vendor-neutral, standards-based MIB, any SNMPv3-capable network device (SNMP engine identity/boot/clock status) with a free 30-day trial of IPNetwork Monitor. Import MIBs, browse SNMP OIDs, create custom SNMP monitors, configure alerts, and monitor any SNMP-enabled network device from a single console.
What Is AVAYA-RTP-MIB?
AVAYA-RTP-MIB defines an interface to RTP media-stream QoS statistics on Avaya VoIP-enabled devices, designed for use by Avaya Services and network operators. It exposes call-quality data such as jitter, packet loss, and MOS score for recent and last-bad-QoS RTP sessions, along with configurable QoS thresholds and dedicated traps for bad-QoS terminations. Its monitoring focus is software/service quality rather than physical hardware - it is used to catch voice-call degradation and repeated bad-QoS conditions on a VoIP platform. It is specific to Avaya's internal VoIP stack rather than an external standard MIB. It is deployed on Avaya IP telephony gateways and media servers, where AVAYA-RTP-MIB SNMP monitoring supports voice-quality troubleshooting and helps catch degraded calls in real time.
IPNetwork Monitor allows you to monitor SNMP objects defined in AVAYA-RTP-MIB. Use the built-in SNMP Monitoring Browser to explore available variables, view their current values and descriptions, and select the objects you want to monitor. You can then create SNMP monitors, configure thresholds, and receive alerts when monitored values change.
Supported Devices
- Avaya VoIP-enabled device (gateway/media server)
Monitoring Examples
An admin would configure thresholds in avRtpThresholdTable and then, when a bad-QoS trap fires, poll avRtpSumTable for the terminated session's statistics and avRtpSessionLocInetAddr/avRtpSessionLocInetAddrType and avRtpSessionRemInetAddr/avRtpSessionRemInetAddrType to identify the local and remote endpoints involved. avRtpLookupTable would then be used to correlate that trap back to the specific RTP session for deeper analysis.
What Can Be Monitored
- RTP jitter
- packet loss
- MOS score
- session local/remote address
- bad-QoS threshold breaches

How to Use in IPNetwork Monitor
Example using avRtpTxQoSTraps OID:
Select an Avaya VoIP-enabled device (gateway/media server) as the target host to create a monitor — the SNMP service should be up and running on it. Click New Monitor, then check SNMP Custom on the Favorites tab, click Next, and confirm the host. On the next page, click Select... to open the built-in SNMP MIB Browser and type avRtpTxQoSTraps into the Find box to locate it in the OID tree, then select it and click OK. The number of avRtpQoSTrap sent so far. On the monitor's Main parameters page you can set the target's SNMP port (default 161), credentials, polling interval, and other settings — see the SNMP Monitor help for details. On the State conditions and Alerting tabs, configure when the monitor should change state and trigger an alert; since this is a Counter32-type OID, Value bounds is the most useful condition here — trigger an alert if the counter increases sharply between polls relative to its normal baseline, since an unexpected spike often reflects a real change in traffic or activity. Click Finish to create the monitor; you can adjust any parameter later.

| avRtpMib | 1.3.6.1.4.1.6889.2.7 | This module defines an interface to RTP sessions QoS statistic gathering capabilities in Avaya's VoIP enabled devices. The MIB, designed for Avaya Services, allows operators to perform the following tasks: 1. View the statistics of recently terminated RTP session. 2. Define QoS related thresholds that define bad-QoS conditions. 3. View the statistics of last session, which experienced bad QoS. 4. Enable a special QoS trap that is sent upon termination of RTP session with bad QoS. 5. Enable a special QoS fault trap that is sent when more than N streams suffer from bad QoS. And a QoS clear trap that is sent when this fault conditions ends. 6. Configure the above traps rate limiting mechanism.
