Cisco Cisco Unified Customer Voice Portal 10.5(1)

High Availability VLANs

Two Layer 2 switches should comprise a single VLAN. There are two reasons for this design:

•

If one switch fails, only a subset of the components becomes inaccessible. The components
connected to the remaining switch can still be accessed for call processing.

•

A Content Services Switch (CSS) and its redundant partner must reside on the same VLAN
in order to send keep-alive messages to each other. If one of the Layer 2 switches fails, one
CSS is still functional.

ASR and TTS

The VoiceXML gateway sends MRCP requests to the ASR/TTS servers in order to perform
voice recognition and text-to-speech instructions that are defined in a VoiceXML document.
The ASR/TTS high-availability configuration and behavior differ between Standalone and
ICM-integrated deployments,

Quality of Service (QoS)

Unified CVP implements Layer 3 QoS defaults on all relevant network paths, and provides a
management interface via the Operations Console to modify QoS settings at each end of
specifically designated data paths. Changes in QoS settings require restart or reboot to take
effect.

Security Best Practices
