We have some problems to make difference between ans machines and human voice, sometimes it works properly and sometimes not.
We set as call_type_recognition : accurate, positive_am_detection and full_positive_am_detection. We need to know what parameters they use, if there are docs which describes the real definition, etc, any help to tune up dialogic.
We saw some public tickets on this topics, they follow:
"Are there any problems with the Answer Machine, fax,... detection ?
Answering machine detection can be tricky to tune up when using Dialogic boards but it is still probably one of the most accurate ways of detecting answering machines even compared to switch call clasifiers. The Dialogic boards and CPD Server peform their best out of the box in North America. In other parts of the world it may be necessary to tune up Dialogic configuration settings. The tune up can be done once the board is installed and working in production. It is necessary to setup recording with CPD Server to get sample greetings for analysis and matching CPD Server log files. Unfortunately this can't be done before the actual installation."
and here bellow the only definition Genesys gives about pam, fpam, etc
Question/Problem
Not detecting answering machines properly. Is seeing a call result of 28 in the CPD logs and the OutBound Contact log.
Answer/Resolution
Can you check in the OCS application for the option call_answer_type_recognition? Currently you have it set to telephony_preset.
I have included the section from the OCS manual about these options. Please try setting the value of this option to one of the am detection ones, such as positive_am_detection, full.... or accurate....
Outbound Contact 6.5
OCS option
call_answer_type_recognition
Type: discretionary
Default value: no_am_detection
Valid values: no_progress_detection, no_am_detection, positive_am_detection,
full_positive_am_detection, accurate_am_detection, telephony_preset
Specifies whether answering machine and fax detection are enabled or disabled. The values and their descriptions are described below.
The value no_progress_detection means that no call progress detection
should occur and that the call will be transferred as soon as it is established.
The value no_am_detection means that answering machine detection is
disabled but detection of all other devices is still enabled.
The value positive_am_detection means that standard answering machine
detection (Positive Answering Machine [PAM] mode) should be used.
The value full_positive_am_detection means that full positive answering
machine detection (Full Positive Answering Machine [FPAM] mode)
should be used.
The value accurate_am_detection means that the duration of the greeting
will be analyzed to make a decision.
The value telephony_preset means that the CPD Server will use the same
method employed by the CPD Server if the value is set to no_am_detection.
Does anybody could make dialogic improve their detection
?
