3. Configure the address and connection settings of the Routing server, referred to as a
Remote Web Service and HTTP remote host (see ''Configuring Remote Web
Services'' on page 282). You must configure the 'Type' parameter of the Remote Web
Service to Routing, as shown in the following example:
Figure 15-48: Configuring Remote Web Service for Routing Server
4. SBC Calls: In the IP-to-IP Routing table, configure the 'Destination Type' parameter of
the routing rule to Routing Server (see Configuring SBC IP-to-IP Routing Rules on
page 685), as shown below:
Figure 15-49: Configuring Routing Rule to use Routing Server
5. Gateway Calls: Enable routing based on Routing server, by configuring the
GWRoutingServer parameter to 1.
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.
