Call Progress Analysis
ca_pamd_qtemp
PAMD Qualification Template: the algorithm to use in PAMD. At present there is only one
template: PAMD_QUAL1TMP. This parameter must be set to this value.
ca_pamd_failtime
maximum time to wait for positive answering machine detection or positive voice detection
after a cadence break. Default Value: 400 (in 10 msec units).
ca_pamd_minring
minimum allowable ring duration for positive answering machine detection. Default Value:
190 (in 10 msec units).
7.13 Default Call Progress Analysis Tone Definitions on
Springware Boards
Table 7 provides call progress analysis default tone definitions for Springware boards. Frequencies
are specified in Hz, durations in 10 msec units, and repetitions in integers. For information on
manipulating these tone definitions, see Section 7.14, “Modifying Default Call Progress Analysis
Tone Definitions on Springware Boards”, on page 71.
7.14 Modifying Default Call Progress Analysis Tone
Definitions on Springware Boards
On Springware boards, call progress analysis makes use of global tone detection (GTD) tone
definitions for three different types of dial tones, two busy tones, one ringback tone, and two fax
tones. The tone definitions specify the frequencies, durations, and repetition counts necessary to
identify each of these signals. Each signal may consist of a single tone or a dual tone.
