Users must configure Avaya Experience Portal with multiple Nuance Speech Server (NSS) connections to have a unique content-id. This content id serves as the grammar id for NSS and is used by nuance components to identify the grammar. Grammar ids are unique within a call but can be reused by different calls.
Grammar Ids are global to NLE. If concurrent calls use the same id to identify different grammars, it is possible that NLE picks the wrong grammar.
To enable the configuration and make the content-id unique, users must add the following in mppconfig.xml with value set to true. This makes the content-id and the session a combination of server name, host name, session, and grammar id.
<parameter name="uri-content-id">true</parameter>
