Call progress analysis always terminates when any of the following events occur: Terminating Condition AG Access Event A dial tone is detected. ADIEVN_CP_DIALTONE A busy tone is detected. ADIEVN_CP_BUSYTONE A reorder tone is detected. ADIEVN_CP_REORDERTONE A SIT (Special Information Tone) is detected. ADIEVN_CP_SIT There is no answer. ADIEVN_CP_NOANSWER A fax or modem answer tone is detected. ADIEVN_CP_CED
Additionally, the you can configure the stopmask parameter in the ADI_CALLPROG_PARMS structure to selectively terminate on the occurrence of any of the following telephone network events: Telephone Network Event AG Access Event A ring tone is detected. ADIEVN_CP_RINGTONE There is a loss of ring tone with no following events. ADIEVN_CP_RINGQUIT The remote party begins speaking (Voice Begin). Check the value field of the event for the voice event. ADIEVN_CP_VOICE, with ADI_CP_VOICE_BEGIN in the value field. The remote party has spoken for a period longer than the first time threshold (Voice Medium). Check the value field of the event for the voice event. ADIEVN_CP_VOICE, with ADI_CP_VOICE_MEDIUM in the value field. The remote party has spoken for a period longer than the second time threshold (Voice Long). Check the value field of the event for the voice event. ADIEVN_CP_VOICE, with ADI_CP_VOICE_LONG in the value field. The remote party has spoken for a period longer than the third time threshold (Voice Extended). Check the value field of the event for the voice event. ADIEVN_CP_VOICE, with ADI_CP_VOICE_EXTENDED in the value field. The remote party stopped speaking (Voice End). Check the value field of the event for the voice event. ADIEVN_CP_VOICE, with ADI_CP_VOICE_END in the value field.
When call progress analysis terminates, an ADIEVN_CP_DONE event is generated.
