Quality of Experience

This chapter describes how to configure the Quality of Experience feature.

Reporting Voice Quality of Experience to OVOC

The device can be configured to report voice (media) Quality of Experience (QoE) to AudioCodes'
One Voice Operations Center (OVOC). The reports include real-time metrics of the quality of the
actual call experience, which are then processed by OVOC.
OVOC is also a VoIP-quality monitoring and analysis tool. It provides comprehensive details on
voice traffic quality, allowing system administrators to quickly identify, fix and prevent issues that
could affect the voice calling experience in enterprise and service provider VoIP networks. IT
managers and administrators can employ OVOC in their VoIP networks to guarantee effective
utilization, smooth performance, reliable QoS levels, and SLA fulfillment.
For information on OVOC, refer to the OVOC User's Manual.

Configuring SNMP for OVOC

Before connecting the device to OVOC, you must configure the SNMP connection between the
device and OVOC. SNMP is used for establishing the initial connection and then for every day
operations including maintenance actions, and fault and performance management.

➢
To configure SNMP for OVOC:
1. Make sure SNMP functionality is enabled, which is the default (see Disabling SNMP).
2. In the SNMP Trusted Managers table (see Configuring SNMP Trusted Managers), either leave
the table without any configuration, or if you want to use Trusted Managers, make sure you
configure a Trusted Manager with the IP address of OVOC.
3. Depending on the required SNMP version, do one of the following:
● For SNMP v2: On the SNMP Communty Settings page (see Configuring SNMP
Community Strings), configure SNMP community strings (or leave at default). Use these
community strings when adding a device in OVOC. In the 'Trap Community String'
parameter, configure the community string for traps.
Make sure that the SNMP settings on the device and on OVOC are identical.
OVOC uses the following default settings:
✔
Trap port: 162
✔
SNMPv2: public for the read-community string, private for read-write
community string, and trapuser for the trap community string.
✔
SNMPv3: OVOCUser for User Name; SHA for Authentication Protocol; AES-
128 for Privacy Protocol; 123456789 for password.
If you have added the device to OVOC by serial number or by auto-detection, you
also need to configure the device with the following ini file parameter settings:
✔
SendKeepAliveTrap = 1 (enables the sending of keep-alive traps to OVOC,
which indicates whether the device is configured for SNMPv2 or SNMPv3)
✔
KeepAliveTrapPort = 1161 (OVOC port to where the device sends keep-alive
traps)
✔
NatBindingDefaultTimeout = 30 (only if the device is located behind NAT)
