CSS Configuration for Call Servers

In Unified CVP Release 4.0, CSS should only be used for load-balancing of Call Servers with
an VRU Only deployment.

Note: The Unified CVP H.323 Service maintains a list of its own Call Servers used as an
interface between the H.323 Service and the Unified ICME for route requests. Retry logic within
the H.323 Service controls requests to the H.323 Service’s Call Servers for routing requests via
the “CallServerList” H.323 Service definitions. If separate Call Servers are used for a Unified
CVP H.323 Service’s interface to Unified ICME for route requests, these Call Servers do not
require configuration within CSS.

CSS Configuration for Call Servers: Service

Configure one Service per Unified CVP Call Server.

The following three services represent Call Servers that will function as IVR Services, or as
routing client interfaces to Unified ICME where a Unified CVP H.323 Service is making the
call request.

Note: If no keepalive retry period is specified, the default value of 5 seconds (recommended
value) is used.

service appserver1

  ip address 10.1.1.5

  keepalive frequency 7 

  keepalive maxfailure 1 

  keepalive type script ap-kal-httpvxml "10.1.1.5"

service appserver2

  ip address 10.1.1.6 

  keepalive frequency 7 

  keepalive maxfailure 1

  keepalive type script ap-kal-httpvxml "10.1.1.6"

service appserver3

  ip address 10.1.1.7 

  keepalive frequency 7

  keepalive maxfailure 1

  keepalive type

  script ap-kal-httpvxml "10.1.1.7"

CSS Configuration for Call Servers: Content Routing Rule

Using the content owner you have defined, define a content routing rule for the Call Servers.
CSS offers many balancing types for choosing an active Call Server. This application uses the
default defined round-robin as the balancing method. Additionally, a primarySorryServer is
defined.

The AS content rule is implemented as a layer 4 routing rule.
