Note

The voice metrics will be collected only in the DSP mode; audio metrics will not be collected for any call routed in the Proxy or Direct Media mode.

By introducing this feature to the SBC1000 and SBC2000, all IP legs of a call the SBC can now report QoE information. Currently, QoE statistics do not get reported on the SBC1000/2000 to SIP Carrier leg of a statistics for the SIP Trunk Provider leg of the call. Statistics such as delay, jitter and packet loss will be reported for the SIP Trunk Leg. This will be a feature unique in the product space.

The SBC1000/2000 with ASM (QoE Agent Server Gateway) will use the SQL server to modify the data used by the Microsoft QoE Services for quality monitoring. The QoE Agent Client gateways (SBC with or without ASM) will notify the QoE Agent Server Gateway with QoE stats for each call in order to update the database of the QoE server. Exchange between QoE Agent Server Gateway and QoE Agent Client Gateway will be handle using SIP NOTIFY.
