What VICIdial Call Progress Detection Is vs AMD
Call Progress Detection classifies far more than answering machines. Here is what CPD does, how it differs from AMD, and where it fits in VICIdial.
Manual VM Status Updates: Track Voicemail Drops on Hand-Dialed Calls
Manual VM Status Updates brings answering-machine message statuses to hand-dialed calls in VICIdial, so voicemail drops on manual calls get logged the same way.
Why VICIdial AMD Misses Machines and Sends Them to Agents
AMD false negatives push answering machines straight to your agents. Here is why VICIdial misses machines and how to tighten detection to catch them.
ANI vs CNAM: what your carrier sends and shows
ANI is the number your call sends; CNAM is the name the far carrier looks up from that number. They are set in two different places.
SIP trunk vs SIP registration: which your carrier needs
Understand the difference between a SIP trunk on IP authentication and one that registers with credentials, and which your carrier expects.
The KHOMP Quick Stats Report: Spotting a Slow Gateway
How the KHOMP Quick Stats Report compares today's processing against past days so you catch a slowing detection gateway early.

Whitelisting your VICIdial server IP with a carrier
How to set up IP authentication: hand your carrier your server's static public IP, configure the peer with no register line, and verify it.
How to connect Commio (thinQ) to VICIdial
Wire Commio, formerly thinQ, into VICIdial using IP authentication for outbound and inbound, then verify with sip show peers and a test call.
Dialing Without Agents to Play a Message in VICIdial
Run a reminder or broadcast campaign that dials a list and plays a recording with no agent logged in. Here is how the auto-message setup works.
How to Tune VICIdial AMD Accuracy When It Is Wrong Too Often
AMD is not perfect out of the box. Here is how to tune VICIdial answering machine detection to your leads and lines and cut the wrong calls.
What Sangoma CPD Detected That Asterisk Can't: SIT Tones
Sangoma CPD classified pre-answer call progress like SIT tones, disconnects, and congestion that Asterisk's AMD cannot identify.
The Dialer KHOMP Admin Tool: Coding Results to Statuses
How the Dialer KHOMP Admin Tool maps the gateway's raw call results onto the VICIdial statuses your reports and routing rely on.
What Answering Machine Detection is and what it does for your campaign
AMD listens to the first seconds of an answered call and decides human vs machine, so agents spend their time on live people instead of voicemail.
VICIdial NOAUDIODATA-Hangup: Drop Silent Dead Calls Fast
The NOAUDIODATA-Hangup option ends calls that reach the AMD routing script with no audio at all, so dead lines never tie up your dialer or an agent.

How Call Progress Detection Lowers Your Dropped-Call Percentage
By labeling non-human answers, CPD lets you exclude them from your drop math, yielding a lower and more accurate dropped-call percentage.
