External grammars. A file containing a set of acceptable customer responses. This file is located 
on a media server and retrieved from the device performing ASR.The Application Server adds this 
pointer to the VXML that it sends to the Gateway. The Gateway then loads the grammar and uses it 
to check ASR input from the caller. 

For a complete explanation of VXML file grammar format, see the Customer Voice Portal (CVP) 
Configuration and Administration Guide. Also, consult the user documentation for your ASR Server 
for a list of supported grammar elements. 

CVP Version 3.0’s support for ASR is defined by the functionality supported by the ASR engines that 
are used in the solution. CVP Version 3.0 supports the Nuance ASR Server and Scansoft.

See the Customer Voice Portal (CVP) 3.0 Bill of Materials for more information about the Nuance 
ASR/TTS Engine and the Scansoft ASR Engine.

There are four different ways that the CVP system can transfer a call using the PSTN or IP. In each case, 
the NAM/ICM initiates the transfer. 

A transfer can be triggered by a number of means, such as:

Call context (that is, DNIS, ANI, Time of Day).

A caller choosing a menu option from a VRU application.

An agent behind an ACD or IPCC signalling a transfer to a different agent.

An agent becomes available.
