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 ITU-T 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 ITU-T Rec. E., Suppl. #2

Positive voice detection accuracy

Positive voice detection speed Positive answering machine detection accuracy Fax/modem detection Intercept detection

Uses both frequency and cadence detection >99% based on tests on a database of real world calls in North America Performance in other markets may vary Detects voice in as little as 1/10th of a second >85% based on application and environment Preprogrammed

Detects entire sequence of the North American Special Information Tone(s) (SIT) Other SIT sequences can be programmed
