ToneScript explained

ToneScript is a description syntax for the characteristics of call-progress tones.

A call progress tone is a pattern of audible tones played to the caller in a telephone call, conveying the status of the call. ToneScript describes the pattern of frequency, cadence, and level of the signal. Many Internet telephony devices support configuration options for users to customize the tones, but standard patterns are provided for various telephone administrations. ToneScript is used in Sipura, Linksys and Cisco family of IP telephony products.
