ICMH); however, this requires that an additional Unified CVP Call Server be attached to the
CICM.

In this call flow model, both the VoiceXML Gateway and the Unified CVP Call Server see two
calls:

•

One for the Switch leg.

•

One for the VRU leg.

For the Switch leg, the Gateway simply provides Gateway capabilities from TDM to VoIP and
call-switching capabilities. For the VRU leg, the Gateway provides VRU voice treatment.

Unified ICMH sees these as a single call routed through different peripherals for different
purposes.

The following figure shows the call flow for this call flow model using SIP without a Proxy
Server.

• In the following diagrams, solid lines indicate voice paths and dashed lines indicate signaling

paths.

• Although the following figure shows two Gateways (one where the call arrives and a separate

one for the VRU leg), these could be the same physical Gateway. Similarly, the Unified CVP
IVR Service in the Operations Console and the PG could be the same physical machine.

• For simplicity, the figure does not illustrate a call flow model for redundancy and failover.

Also, the Gatekeeper is not shown.
