1.1. Introduction to Learn Mode
Computer telephony applications use Intel telecom boards that are often installed "behind" proprietary private branch exchange (PBX) or key systems. This type of configuration can pose challenges for the developer in terms of integrating the application with each vendor's individual PBX or key system. The challenge occurs because each switch does not always produce standard telephone company call progress tones such as busy, dial tone, or ringback.
To remedy the situation, the standard call progress tone detection algorithms within the telecom board must know these custom frequencies and cadences.
Although the PBX Expert/32 utility is available for learning tones, the learn mode software gives you the flexibility to integrate tone learning capability directly in your computer telephony applications. The PBX Expert/32 utility (previously called PBXpert/32) calls on the learn mode API under the hood to accomplish PBX tone learning. For more information on the PBX Expert/32 utility, see Intel Communications Systems Products website: http://www.intel.com/network/csp/.
The learn mode software is supported on specific boards and runs on Windows operating systems. It consists of learn mode library and header files, device drivers, firmware, and documentation to help you develop applications with tone learning capability. The learn mode library supplies functions that interface with the voice driver. For information on hardware that supports the learn mode API, see the release guide accompanying the system release.
The learn mode software works together with the voice library global tone detection feature to learn tones and capture tone descriptions. For more information on global tone detection, see the Voice Software Reference -- Features Guide.
