Call Progress Analysis

Busy tone detection

Default setting designed to detect 74 out of 76 unique busy/congestion

tones used in 97 countries as specified by CCITT Rec. E., Suppl. #2.

Default uses both frequency and cadence detection. Application can

select frequency only for faster detection in specific environments.

Ring back detection

Default setting designed to detect 83 out of 87 unique ring back tones

used in 96 countries as specified by CCITT Rec. E., Suppl. #2. Uses both

frequency and cadence detection.

Positive voice detection accuracy

>98% based on tests on a database of real world calls in North America.

Performance in other markets may vary.

Positive voice detection speed

Detects voice in as little as 1/10th of a second

Positive answering machine detection

85% based on application and environment

accuracy

Fax/modem detection

Preprogrammed

Intercept detection

Detects entire sequence of the North American tri-tone. Other SIT tones

can be programmed.

Dial tone detection before dialing

Application enable/disable

Supports up to three different user-definable dial tones

Programmable dial tone drop out debouncing
