ViciAMD

ViciAMD is the detection engine that ships inside VICIdial to decide what answered each outbound call. It rolls together the two jobs people usually name separately: figuring out whether the call connected at all, and figuring out whether the thing that answered is a live person or a recording. When it makes its decision, it writes a status onto the lead and the dialer acts on that status — connecting the person to an agent, hanging up, or moving on to a recorded message.

Under the hood, ViciAMD is VICIdial's implementation of AMD (answering machine detection) sitting on top of CPD (call progress detection). You enable it per campaign and then tune two things: how long it listens before deciding, and how strict it is about calling something a machine. It can also handle Beep detection, so that once it decides a machine answered, a Voicemail drop starts playing right after the greeting's tone rather than talking over the greeting, which leaves a clean, full message on the recipient's voicemail.

Tuning without losing people

The whole game with ViciAMD is balance. Crank up sensitivity and you catch more machines, but you also create more cases where a real Live answer gets misread and dropped — that is an AMD false positive, and every one is a paying lead you threw away. Loosen it and machines slip through to your agents, eating the talk time you were trying to protect. The sensible approach is to start conservative, watch your detection reports for several days, and nudge the settings a little at a time while keeping an eye on how many real answers got hung up on. Voice and accent vary by market, so a setting that works for one campaign may not fit another, and the same campaign can behave differently when you switch carriers. Treat the tuning as something you revisit, not a switch you set once and forget. This is operational guidance, not legal advice.
