Chapter 1      Introduction
NAM/ICM Scripting
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. 
Note
For a complete explanation of VXML file grammar format, see the Internet Service Node (ISN) 
Configuration and Administration Guide
. Also, consult the user documentation for your ASR Server 
for a list of supported grammar elements. 
ASR Engine Support
ISN Version 2.1’s support for ASR is defined by the functionality supported by the ASR engines that are 
used in the solution. ISN Version 2.1 supports the Nuance 8.0 ASR Server and Speechworks.
See the Internet Service Node (ISN) Release Notes for Release 2.1 for a list of differences between the 
Nuance ASR/TTS Engine and the Speechworks ASR Engine.
Transferring Calls with ISN 
There are four different ways that the ISN 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.
