Syslog Fields for Answering Machine Detection (AMD)

The syslog message can include information relating to the Answering Machine Detection (AMD) feature. AMD is used to detect whether a human (including a fax machine), an answering machine, silence, or answering machine beeps have answered the call on the remote side.

■

AMDSignal – the field can acquire one of the following values:

●

voice (V)

●

answer machine (A)

●

silence (S)

●

unknown (U)

■

AMDDecisionProbability – probability (in %) success that correctly detects answering type

Below is an example of such a syslog message with AMD information:

CallMachine:EVENT_DETECTED_EV - AMDSignal = <type – V/A/S/U>, AMDDecisionProbability = <percentage> %

If there is no AMD detection, the AMDSignal field is shown empty (i.e. AMDSignal = ).
