Cisco Cisco Unified Customer Voice Portal 11.0(1) Installation Guide

Migrating from Queue and Transfer to Comprehensive with SIP

Migration from the Queue and Transfer deployment model to the Comprehensive deployment
model with SIP involves the following tasks:

•

Making configuration changes in ICM, in the CVP Call Server, and in the ingress gateways.

•

Optionally, deploying new SIP Proxy Servers and/or DNS Servers.

•

In most cases, deploying and configuring additional gateways.

•

Adding Cisco CSS switches if the number of servers and the desired failover and redundancy
model for your deployment necessitates it.

To perform this migration, perform the following steps:

Modify the ICM configuration as follows. Refer to the ICM Configuration Guide for Cisco ICM
Enterprise Edition for instructions.

a.

Change the current Type 5 NetworkVRU to Type 10. Assign a VRU Transfer Label to
this VRU, which will cause the call to be transferred to a VoiceXML Gateway. Duplicate
this label for each CVP peripheral routing client.

b.

Create a new NetworkVRU of Type 10, with one "DUMMY" label for each CVP routing
client.

c.

Associate each CVP peripheral with this new Type 10 NetworkVRU.

Modify the CVP Call Server configuration using the Operations Console, to ensure that the
VRU Transfer Label length is properly set in the ICM tab for each CVP Call Server.

Introduce the (optional) SIP Proxy Servers at this point, or configure the existing DNS Servers
to be used for SIP message routing.

Configure the ingress gateways to use SIP. Configure each ingress gateway outgoing VoIP
dial-peer to use SIP rather than session target ras. If SIP Proxy Servers are being used, configure
the dial-peers to target those servers. If not, then configure the dial-peers to target one or more
CVP Call Servers.

Configure the SIP Proxy Server (if present) or the SIP tab in the CVP Call Server configuration
in the CVP Operations Console so that calls to the VRU Transfer Label will target the VoiceXML
gateways. Be sure to allow for the variable correlationId suffix on the VRU Transfer Label.

Introduce CSS devices at this point, if so desired. Configure these devices as described in the
Configuration and Administration Guide for Cisco Unified Customer Voice Portal.

Configure the VoiceXML gateways as you would in a new installation.
