FR1302 - Ability to Increase Gain on Incoming Calls

This feature allows the developer to increase the gain (db level) of an incoming call, and to adjust it to a desired level. Low level incoming calls can cause wrong detection and failure in the functionality of the application. The ability to increase the gain on incoming calls can be very helpful and can prevent problems by adjusting the incoming level to the appropriate level.

This feature introduces two new ICBs (0x26 and 0x0026) which are included in the API Reference.

FR1169 - Report Actual NFS Server ID When Using VIF Bypass

The Vocabulary Index File (VIF) Bypass function allows playing a file directly from an onboard cache, and bypasses the VIF lookup function for determining the file location. This feature retrieves the actual NFS server ID, where the file is stored, and reports it to the application.
