Call Progress (CP) Software

GAO Research Inc. (www.GAOResearch.com) is offering its Call Progress (CP) software for telephone network systems. It provides full call progress tone detection and generation functionality and operates on PCM samples.
The Call Progress (CP) software consists of two user-callable functions that perform the detection, generation, and initialization operations.
Using a tonal signaling standard, it is able to acquire connections between subscribers in telephone network systems and to indicate the status of the incoming and outgoing phone calls. The software module allows for such signals as Dial Tone, Busy Tone, Congestion Signal, Ring Back and Off Hook.
Apart from the above, this software also features low data and program memory requirements and can be easily configured to different cadences and tones.
This Call Progress (CP) software belongs to GAO’s family of Telephony Software. This line includes a wide variety of telephony modules such as Dual Tone Multi-Frequency (DTMF) Software which is widely used in interactive control applications such as telephone banking, electronic mail systems, and many other menu-driven operations that respond to digits entered from a telephone, Acoustic Echo Cancellation Software (AEC) and MF R1/R2 software. GAO provides a complete package for telephony that includes speech compression modules and telephony modules.
