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.

The syslog message includes the following AMD-related fields:

■

AMDSignal: This field can have one of the following values:

●

"V" - voice

●

"A" - answer machine

●

"S" - silence

●

"U" - unknown

■

AMDDecisionProbability: The probability (in %) success that the correct answering type was detected.

The following shows an example of 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 ("AMDSignal = ").
