Call Progress Tones (SPA3102 and SPA8800)
The SPA3102 and the SPA8800 have configurable call progress tones. Call
progress tones are generated locally on the ATA, so an end user is advised of
status (such as ringback). Parameters for each type of tone (for instance a dial tone
played back to an end user) may include the following specifications:
Number of frequency components
Frequency and amplitude of each component
Cadence information
When one VoIP account is shared between the FXS and PSTN Lines, the following
parameters are recommended to be set. For more information, see the Regional
page in the ATA Voice Field Reference, on page 110.
