15.6.4 Configuring QoS-Based Routing by Routing Server

You can configure the device to allow the routing server to route calls based on QoS
metrics (media and signaling). The device collects QoS metrics per IP Group that you have
configured to operate with the routing server ('Used by Routing Server' parameter
configured to Used in the IP Groups table). The metrics include the following:

Signaling: ASR, NER, and ACD

Media: packet loss (Rx/Tx), packet delay (local/remote), jitter (local/remote), MOS
(local/remote), audio bandwidth (Rx/Tx), video bandwidth (Rx/Tx), and total bandwidth
(Rx/Tx)
The device collects QoS metrics for both incoming call traffic and outgoing traffic from the
remote endpoint. It sends the QoS reports to the routing server, where each report can
contain the status of up to 100 IP Groups. If more than 100 IP Groups exist, the device
sends multiple QoS reports (sequentially) to the routing server. The device sends the
reports every user-defined period. The routing logic of where to route calls based on QoS
("good", "fair", and "bad") is configured on the routing server.

To configure the device for QoS-based routing by routing server:
1. Open the Web Service Settings page (Setup menu > IP Network tab > Web Services
folder > Web Service Settings), and then do the following:
a. From the 'Quality Status' drop-down list (RoutingServerQualityStatus), select
Enable to enable QoS-based routing.
b. In the 'Quality Status Rate' field (RoutingServerQualityStatusRate), enter the rate
(in sec) at which the device sends QoS reports.

c. Click Apply.
2. Open the Remote Web Services table (see Configuring Remote Web Services on
page 281 ), and then for the Remote Web Service entry that you configured for the
routing server, do the following:
a. From the 'Type' drop-down list (HTTPRemoteServices_HTTPType), select QoS.
b. Click Apply.
3. Enable voice quality monitoring and RTCP XR, using the 'Enable RTCP XR'
(VQMonEnable) parameter (see Configuring RTCP XR on page 729).
Note:
quality monitoring and RTCP XR.
