Configuring Customizable Ivr - HP FlexNetwork MSR Series Configuration Manual

Configuring customizable IVR

Overview
Interactive voice response (IVR) is extensively used in voice communications. The IVR system
enables you to customize interactive operations and humanize other services. If a subscriber dials
an IVR access number, the IVR system plays the prerecorded voice prompts to direct the subscriber
about how to proceed, for example, dial a number.
Advantages
A conventional interactive voice system uses fixed audio files and operations. IVR enables you to
customize your own interactive system by adding, modifying, and removing audio files. IVR has the
following advantages.
Customizable voice prompts
Voice prompts can be saved as audio files, which must be .wav files. You can record personalized
voice prompts and upload the audio files to the voice devices. The customizable voice prompts can
be played to subscribers. The adding, modifying and removing operations in the IVR system are
simple and easy to use, and the configurations take effect instantly.
Various codecs
The IVR system supports four codecs for voice prompts: G.711alaw, G.711ulaw, G.723r5, and
G.729r8. Each kind of codec has its advantages and disadvantages:
•
G.711alaw and G.711ulaw provide high quality of voice while requiring greater memory space.
•
G.723r53 and G.729r8 provide relatively low quality of voice while requiring less memory
space.
Flexible node configuration
To simplify configuration, the IVR system uses nodes as basic units for configuration. You can define
three types of nodes: Call node, Jump node, and Service node. Each node type has a single function,
and you can combine them to realize complex functions.
•
Call node—Executes a secondary call.
•
Jump node—Jumps to another node according to the input of the subscriber.
•
Service node—Executes various operations, such as executing an immediate secondary call,
auto jumping, terminating a call, and playing an audio file.
Customizable process
The IVR system simplifies tasks such as configuring custom IVR access numbers, voice prompts,
and combinations of keys and voice prompts, making customization of interactive process easy.
