Sip Caller's Answering Machine Detection uses real-time speech analysis to distinguish between a live person and a voicemail. Calls are then routed down different branches — agents only ever speak to humans, while machines get a pre-recorded message timed to finish after the beep.

Real-time speech analysis on every answered call
Different call flow branches for humans versus machines
Automatic timing around voicemail greetings so messages start cleanly
Works across all three dialer modes (predictive, progressive, power)
Measurable impact on agent productivity and campaign reach

Real-time Analysis

AMD runs the instant a call is answered, detecting speech patterns that distinguish a live human from a voicemail greeting.

Human-vs-Machine Routing

Agents only ever receive calls confirmed as live humans. Machines route to a separate flow — typically a scheduled voicemail drop.

Voicemail Timing

The system waits for the answering machine greeting to finish before playing its message. No talking over the beep.

Productivity Boost

Typical campaigns see a significant drop in agent idle time and a matching rise in connected talk minutes.

Dialer-mode Agnostic

AMD runs identically whether the campaign uses predictive, progressive or power dialing.

Tunable Thresholds

Adjust sensitivity and timeouts per campaign so short greetings aren't misclassified as humans.
